[TRIO] Add TRIO105: SyncTrioCall

[qdegraaf]

Summary

Adds TRIO105 from the flake8-trio plugin. The MethodName logic mirrors that of TRIO100 to stay consistent within the plugin.

It is at 95% parity with the exception of upstream also checking for a slightly more complex scenario where a call to start() on a trio.Nursery context should also be immediately awaited. Upstream plugin appears to just check for anything named nursery judging from the relevant issue.

Unsure if we want to do so something similar or, alternatively, if there is some capability in ruff to check for calls made on this context some other way

Test Plan

Added a new fixture, based on the one from upstream plugin
