build(deps): bump uuid and @actions/core in /.github/actions/send-email

Removes [uuid](https://github.com/uuidjs/uuid). It's no longer used after updating ancestor dependency [@actions/core](https://github.com/actions/toolkit/tree/HEAD/packages/core). These dependencies need to be updated together.


Removes `uuid`

Updates `@actions/core` from 1.10.1 to 1.11.1
