robobun f6f7e66a2c Add back --only flag to test runner (#23385) 
Fixes #23380 - this is a use-case for the `--only` flag that I missed

Adds back the `--only` flag. When running `bun test` on a full test
suite, without this flag it will run only that test in its file, but it
will run all other tests from other files. With this flag, it will not
run things from other files.
