Support using id_token as the Bearer token for requests

[kzbt]

Is your feature request related to a problem? Please describe.
I'm not an oauth2 or openid expert, so I'm not sure if this makes sense.

Right now when using the Authorization Code grant type with openid, we get back 3 tokens: 1) access_token 2) id_token and 3) refresh_token. Due to some limitations with auth providers sometimes we can only use the id_token in our applications. However, Insomnia always uses the access_token in requests.

Describe the solution you'd like
Add a configuration option in the OAuth2 options to use id_token for a particular request

Describe alternatives you've considered
Currently I'm copying and pasting the id_token field to the access_token field

Additional context
NA

if you got here by searching for a solution, like me, apparently Insomnia now supports this in an undocumented (at least none that I could find) way:

1. configure OAuth2 as usual
2. make sure to request a scope which provides the relevant token
3. go to the Headers tab
4. Add Authorization header, where value is:
   • for id_token: Bearer {% request 'oauth2-identity', '', 0 %}
   • for refresh_token: Bearer {% request 'oauth2-refresh', '', 0 %}

Nice workaround! It's a little tricky ugly since we can disable auth and still get request authorized but still is a valid solution!

I think on implement this suggestion for fun, thinking on how to display this info on Oauth window...
