fix: Correct IndentationError in get_pr_review_comments.py

This commit fixes an IndentationError in the
`scripts/gha/get_pr_review_comments.py` script. The error was
caused by a malformed comment on the final print statement within
the main loop.

The stray comment has been removed and the print statement's
newline character has been ensured. This resolves the syntax error
and allows the script to be parsed and executed correctly.
