When using the ansible.builtin.assert module, highlight the that argument just like a when.

Alternatives

Additional context

Quoting from https://docs.ansible.com/ansible/latest/collections/ansible/builtin/assert_module.html:

that: A list of string expressions of the same form that can be passed to the 'when' statement.

Yes, assert...that is quite a special condition. It's going to be tricky to implement. Essentially, it shouldn't be done in TextMate grammar as that would make it really complex and verbose for just this one case. But in the same time, implementing that in the dynamic syntax-highlighting in language server, might require implementing jinja syntax highlighting there too... which I'm not so enthusiastic about...

I'll investigate the options
