GitHub actions: add pipe to allow for multiline script run (#20684)
This was added in #20454 and #20455, but is causing issues when trying to run those actions in the mirror repos:

```
 [36;1mif [[ -z "$TOKEN" ]]; then echo '::error::The secret API_TOKEN_GITHUB must be set.' exit 1 fi[0m
 shell: /usr/bin/bash -e {0}
 env:
   TOKEN:
 line 2: syntax error: unexpected end of file
```
