chore: remove copilot instructions

Recent models like GPT-5 have broken these instructions. As such, I
don't think that it's worth having these around anymore. I think that
longer term it may be better to have a policy of having people disclaim
which models they use in commit footers rather than having a "don't use
this tool" policy, which people are just going to work around and
ignore.
