[johan-jnn]

Based on swagger-api/swagger-codegen#9493

Pull Request

Note :
This PR has the exact same purpose than this one, but for the v3 version of swagger-codegen.

Description

Based on how PHP template deals with Bearer auth, I did the same in the typescript-fetch mustache template.

The token should be passed to the accessToken configuration key (as in the php code). If a function is given, we call it without the scope argument (as authorized in the definition of accessToken).

How to Test

Using this authorization schema, then generate using the -l typescript-fetch flag, and see the Bearer authentification in the Authorization header being passed in the FetchParamCreator of the model.

Notes

Maybe I should add some java tests to test this, but idk how to write/test java in such big project.
