(maint) Move support exclusion to VCR filter

[AdmiringWorm]

Description Of Changes

This updates the settings.kts file by moving the support filter from VCS
to the VCS filter.

Motivation and Context

This is believed to be the correct place to be able to filter out the
support branch, while still being able to manually initiate a build on
the branch.
