Subject: [PATCH] CI: use bash for get-base-ref-size job

Same change as done in https://github.com/InfiniTimeOrg/InfiniTime/commit/c3295d6d2a325f9a7418b15b943342635026926e
But for get-base-ref-size job

The variable substitution I introduced are bash features. So they don't work with sh.

Update the size job to use `bash` instead of `sh` as shell
