Update Anthropic Foundry Identity Token Credential

Problem Statement

Problem Statement

The current implementation accepts only a static AccessToken, which is suitable for scenarios like an ApiKey that remains valid indefinitely during the client's lifetime. However, this approach fails for other AccessToken types that expire and require periodic renewal.

To address this, the change delegates token management to the specialized TokenCredential implementation.

Thanks for your PR! Just had a few minor comments

Would you be able to retarget this to the next branch?

Would you be able to retarget this to the next branch?

Sure, done!

@rogerbarreto There's a lint failure 😞

[rogerbarreto]

Something is off.

This is what I get from my current branch, up-to-date, lint and format don't require any change.

@sd-st, merged next into the PR to see if a new pipeline run can work.

[sd-st]

Hey @rogerbarreto do you mind rebasing this? Looks like something got messed up and the diff is huge now.

@sd-st, Done (from what I could remember), I also noticed with the latest next branch, a bunch of Unit Tests are failing... unrelated to this PR.

Note

The process of the automation / codegen you are using in the repo is also messing up with all the PR's and possibly touching/altering / force-pushing into PRs git history is the reason.
Ideally for a healthy contribution environment this should be avoided.

Looks like there's a lint failure from the formatting
