feat: Allow adding iss for the oidc assumable role

[whatisusername]

Description

Add the iss condition to the assumable OIDC role.

Motivation and Context

The current implementation of the assumable OIDC role does not include the iss condition in the trust policy. This update follows the pattern introduced in OIDC role PR #507 to ensure consistency and compatibility with common OIDC providers.

Breaking Changes

None. This change is backward-compatible as it only adds an additional condition without altering existing functionality.

this is not correct - however, you can use provider_trust_policy_conditions to provide generic assume role conditions already so closing this out
