Misleading "please retry" message when checks are pending

[sersorrel]

When a check is still pending, the bot will tell you to try again later:

nixpkgs-merge-bot/nixpkgs_merge_bot/commands/merge.py

Line 141 in c0cdb51

msg = "One or more checks are still pending, please retry after they are done. darwin checks can be ignored."

but it's stated in the nixpkgs README (see NixOS/nixpkgs#305553) that the bot "patiently waits for ofBorg to finish before attempting the merge again".

If the bot will in fact automatically retry the merge once checks are done, the message should probably say something closer to:

One or more checks are still pending, will automatically retry after they are done (darwin checks are ignored).

At least in theory. I heard in some cases that retry doesn't work.
