Mark tokens as sensitive in data sources (#416)

* Mark tokens as sensitive in data sources

Mark the following attributes as sensitive to prevent them from being
logged or displayed in Terraform output:

- data.coder_workspace_owner.me.oidc_access_token
- data.coder_workspace_owner.me.session_token
- data.coder_external_auth.example.access_token

This follows the same pattern as ssh_private_key and agent token
which are already marked as sensitive.

Fixes #266

* Update documentation for sensitive token attributes

Regenerate documentation to reflect that oidc_access_token, session_token,
and access_token are now marked as sensitive in the schema.
