feat(fake-auth): add callback event to fake auth handler

[ToWe0815]

The PR adds a callback event to the fake auth handler to enable the user the manipulation of the created identity before its usage.

A typical use case could be the creation of several mock "users", all having different claims/roles for testing purposes. These "users" are distinguished by having different fake ids, that are getting set via the "x-zitadel-fake-user-id" header when testing typical auth scenarios.

Hey @ToWe0815
The tests /linting are failing

[ToWe0815]

Hey @buehler
Should be fixed now!

[buehler]

Did you update to v6?
GitHub says there are merge conflicts

[ToWe0815]

Done, my bad.

[ToWe0815]

@buehler Is there anything I need to do for this change to be merged? Am I missing something?

[buehler]

Hey @ToWe0815

Yes, please make sure that the tests are running. Otherwise, I cannot merge it.

Hey @buehler

As far as I can see the tests are failing because of a known vulnerability in the 'BouncyCastle.Cryptography' package:
/home/runner/work/zitadel-net/zitadel-net/src/Zitadel/Zitadel.csproj : error NU1902: Warning As Error: Package 'BouncyCastle.Cryptography' 2.2.1 has a known moderate severity vulnerability, https://github.com/advisories/GHSA-8xfc-gm6g-vgpv [/home/runner/work/zitadel-net/zitadel-net/Zitadel.sln]

There are already 2 open PRs regarding this issue (among other similar things):
#930
#926

Semi-Off topic:
The whole project seems to be a bit shaky right now and I think you should take some time to look into open PRs & Issues.

ServiceAccountTest.Should_Throw_With_Meaningful_Error() fails locally on my machine, because the Token Endpoint of the project's Zitadel instance responds with a HTTP 500 when a meaningful error is expected by said test case. This might be due to a change on Zitadel's side and cannot come from my changes made in this PR, since I only added functionality to auth mocking.

Also buf generate doesn't seem to run automagically on build anymore:
#925

I had to execute buf generate manually to make it work, but I'm also not deep enough into the topic to find/fix the problem's source right now.

Hey @ToWe0815
Thanks to a PR, all the deps are updated. You should be able to fix the linting errors :)
