[ENHANCEMENT, `robot.toml`] Make `no-status-rc` accept conditions (like `enabled` does)

[Noordsestern]

Gude!

I have a profile that I'd like to active in CI environment:

[profiles.ci]
enabled = { if = "environ.get('CI') == 'true'" }
no-status-rc = { if = "environ.get('CI_COMMIT_REF_NAME') == 'main'" }

The profile is automatically enabled when the environment variable CI is set. Which is awesome. Now depending on the branch ci is working on, want the status-rc to be returned or not.

Now, I can duplicate the CI-job, but it would be very convenient when boolean configurtions (like no-status-rc) would accept conditions just like enabled.

Background: feature branches must fail an be reviewed before being merged. Test runs on main must not fail the pipeline, as their results are reported in test reporting tool.
