fix: add more files which trigger the mise validation task

Related to https://gitlab.com/gitlab-com/gl-infra/gitlab-dedicated/team/-/issues/8290#note_2430398785

Unfortunately when common-ci-tasks was upgraded, leading to mise being upgraded, the mise validation task did not run, since there were no changes to .tool-versions.

This led to an issue where an common-ci-tasks MR succeeded only because the mise validation task was not run. Had it run, the problem would have surfaced in branch.

This also means that downstream MRs fail through no fault of their own.

This change attempts to fix this problem by adding more cases in which the mise validation task is run.
