fix: --yes option for protonup

[SteveLauC]

Standards checklist:

• The PR title is descriptive.
• I have read CONTRIBUTING.md
• The code compiles (cargo build)
• The code passes rustfmt (cargo fmt)
• The code passes clippy (cargo clippy)
• The code passes tests (cargo test)
• Optional: I have tested the code myself

For new steps

• Optional: Topgrade skips this step where needed
• Optional: The --dry-run option works with this step

If you developed a feature or a bug fix for someone else and you do not have the
means to test it, please tag this person here.

Closes #559

Note: while updating then protonup (when invoked through topgrade) - it did not seem to output any informational statements. So nothing to say it was working, the updating looked "stalled". Or "hung" for a couple of minutes. With not indicators. However the update did occur successfully, upon waiting long enough. And with a discovery afterwards for re-checking again to see no more updates.

ok it seems to work.

Happy to hear this!

I reproduced this on my host, but it seems to be a bug (or feature?) of protonup:
