Fix a few issues with the C generator (part 2) (#20227)

* [C] Don't convert post body strings to JSON

If the body provided for the api request is a just a string itself,
don't try to convert it to JSON, simply submit the string.

* [C] Implement BearerToken authentication

* [C] Handle nullable fields correctly

* [C] Fix implementation of FromString for enums

* [C] Update the test schemas to cover the changes

* Update samples

* Fix the updated samples

* [C] Add the new samples folder to the CI workflow

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:

+# C API client for sample_api
+
+## Overview
+This API client was generated by the [OpenAPI Generator](https://openapi-generator.tech) project. By using the [OpenAPI spec](https://openapis.org) from a remote server, you can easily generate an API client.
+
+- API version: 0.1.9
+- Package version: 
+- Generator version: 7.11.0-SNAPSHOT
+- Build package: org.openapitools.codegen.languages.CLibcurlClientCodegen
+
+## Installation
+You'll need the `curl 7.58.0` package in order to build the API. To have code formatted nicely, you also need to have uncrustify version 0.67 or later.
+
+# Prerequisites
+
+## Install the `curl 7.58.0` package with the following command on Linux.
+```bash
+sudo apt remove curl
+wget http://curl.haxx.se/download/curl-7.58.0.tar.gz
+tar -xvf curl-7.58.0.tar.gz
+cd curl-7.58.0/
+./configure
+make
+sudo make install
+```
+## Install the `uncrustify 0.67` package with the following command on Linux.
+```bash
+git clone https://github.com/uncrustify/uncrustify.git
+cd uncrustify
+mkdir build
+cd build
+cmake ..
+make
+sudo make install
+```
+
+## Compile the sample:
+This will compile the generated code and create a library in the build folder which has to be linked to the codes where API will be used.
+```bash
+mkdir build
+cd build
+// To install library to specific location, use following commands
+cmake -DCMAKE_INSTALL_PREFIX=/pathtolocation ..
+// for normal install use following command
+cmake ..
+make
+sudo make install
+```
+## How to use compiled library
+Considering the test/source code which uses the API is written in main.c(respective api include is written and all objects necessary are defined and created)
+
+To compile main.c(considering the file is present in build folder) use following command
+-L - location of the library(not required if cmake with normal installation is performed)
+-l library name
+```bash
+gcc main.c -L. -lsample_api -o main
+```
+Once compiled, you can run it with ``` ./main ```
+
+Note: You don't need to specify includes for models and include folder separately as they are path linked. You just have to import the api.h file in your code, the include linking will work.
