[docs] Creating a new generator

FAQ has been split into multiple smaller documents to better categorize
and allow users to find what they're looking for (in docs folder or in
new website).

Release summary information (versioning strategy and cadence) has been
migrated from the Wiki and clarified a bit.

Also adds copy button for all code snippets in website.

-#### Bug Report Checklist
-
-- [ ] Have you provided a full/minimal spec to reproduce the issue?
-- [ ] Have you validated the input using an OpenAPI validator ([example](https://apidevtools.org/swagger-parser/online/))?
-- [ ] What's the version of OpenAPI Generator used?
-- [ ] Have you search for related issues/PRs?
-- [ ] What's the actual output vs expected output?
-- [ ] [Optional] Bounty to sponsor the fix ([example](https://www.bountysource.com/issues/66123212-javascript-client-produces-a-wrong-object-for-a-string-enum-type-that-is-used-with-ref))

 ### [6.3 - History of OpenAPI Generator](#table-of-contents)
 
 OpenAPI Generator is a fork of [Swagger Codegen](https://github.com/swagger-api/swagger-codegen). In view of the issues with the Swagger Codegen 3.0.0 (beta) release and the disagreement on the project's direction, more than 40 top contributors and template creators of Swagger Codegen decided to fork Swagger Codegen and maintain a community-driven version called "OpenAPI Generator". Please refer to the [Q&A](docs/qna.md) for more information.

 The following are vendor extensions supported by OpenAPI Generator. The list may not be up-to-date, the best way is to look for "x-" in the built-in mustache templates.
 
-### All generators (core)
-
-#### Enum
-
-`x-enum-varnames` can be used to have an other enum name for the corresponding value.
-This is used to define names of the enum items.
-
-`x-enum-descriptions` can be used to provide an individual description for each value.
-This is used for comments in the code (like javadoc if the target language is java).
-
-`x-enum-descriptions` and `x-enum-varnames` are each expected to be list of items containing the same number of items as `enum`.
-The order of the items in the list matters: their position is used to group them together.
-
-Example:
-
-```yaml
-WeatherType:
-  type: integer
-  format: int32
-  enum:
-    - 42
-    - 18
-    - 56
-  x-enum-descriptions:
-    - 'Blue sky'
-    - 'Slightly overcast'
-    - 'Take an umbrella with you'
-  x-enum-varnames:
-    - Sunny
-    - Cloudy
-    - Rainy
-```
-
-In the example for the integer value `42`, the description will be `Blue sky` and the name of the enum item will be `Sunny` (some generators changes it to `SUNNY` to respect some coding convention).
