Closes #18037

Create and push the expected tag to grafana-dev repository
and use this instead for running the end to end tests
for the release.

The `oauth_state` cookie used to be created with the SameSite value set
according to the `cookie_samesite` configuration.
However, due to a Safari bug SameSite=None or SameSite=invalid are treated
as Strict which results in "missing saved state" OAuth login failures
because the cookie is not sent with the redirect requests to the OAuth
provider.
This commit always creates the `oauth_state` cookie with SameSite=Lax
to compensate for this.

* Add types and rewrite datasourceChanged to async/await

Closes #18159

* Imperative mood

The English language suggests that when giving out instructions or considerations is best to use imperative mood as the writing style. Done as part of this commit:

- some worth smithing to match this style
- changed the format to match the fact that this is commonly read as part of a text box when opening up your PRs
- and extended a few descriptions to make it more friendly for newcomers 

* Auth Proxy: Include additional headers as part of the cache key

Auth proxy has support to send additional user attributes as part of the
authentication flow. These attributes (e.g. Groups) need to be monitored
as part of the process in case of change.

This commit changes the way we compute the cache key to include all of the
attributes sent as part of the authentication request. That way, if we
change any user attributes we'll upsert the user information.

Make sure all data is sent to API to be able to select correct archive version.
