Update the Platform TCK pull request template.md to CC committer list for created pull requests

See https://github.com/jakartaee/platform-tck/blob/main/.github/pull_request_template.md which contains people that aren't currently committers:

CC @alwin-joseph @anajosep @arjantijms @cesarhernandezgt @dblevins @m0mus @edbratt @gurunrao @jansupol @jgallimore @kazumura @kwsutter @LanceAndersen @bhatpmk @RohitKumarJain @shighbar @gthoman @brideck @OndroMih @dmatej @starksm64 @scottmarlow

Would be good to instead use code owners file that can be listed in the platform tck root that specifies who should be pinged about issues.
