cylc lint is catching things in multi-line strings

[blaylockbk]

Description

cylc lint is flagging items in multi-line strings. I expected these lines to be skipped by the linter.

Reproducible Example

For this flow.cylc file

[meta]
    title = This is my workflow
    description = """
        This workflow demonstrates how linting flags things in multi-long comments

        Just wanted to say this is how you set UTC mode...

        [scheduler]
            UTC mode = True
    """

[scheduler]
    UTC mode = True

[scheduling]
    initial cycle point = 2024-01-01T00:00Z
    final cycle point = 2024-01-02T00:00Z

When I run cylc lint I get this...

[S003] flow.cylc:8: Top level sections should not be indented.

Checked <myWorkflowDirectory> against ['728', 'style'] rules and found 1 issue.

Expected Behaviour

Line 8 is part of the multiline description and is not "cylc". I expected the linter to ignore these lines.

Ha, good spotting - I guess we didn't expect to see valid Cylc config inside string values!

Workaround, for the moment - put this sort of thing in a comment.

Similar problem to #6348. The linter would need to be stateful to handle situations like this which would require a rethink in the approach.
