### What
Rename all JSDoc OAS `@schema` and `$ref: #/components/schemas/` from snake_case to PascalCase, `foo_bar -> FooBar`
Extra scope: Remove `x-resourceId` from JSDoc OAS.
### Why
Classes use PascalCase as a convention but the OAS @schemas describing them were using snake_case. OAS code generators tend to use the schema name when generating typed models.
In order to avoid mismatch between source code, the OAS, and the generated client code, it is advised to align OAS @schemas formatting to the classes they represent.
Extra scope: x-resourceId is not a widely used OAS property. It's current usage in our OAS does not provide additional value. Therefore, we recommend to remove it in order to have one less item to maintain.
### How
Good old search & replace. Regex search to further make sure we didn't miss any.
The scope is limited to `@schema` definition and their usage in `$ref: #/components/schemas/`.
### Test
* Ran OAS validator.
* Ran docs build script.
Expect no visible changes to the documentation.
