Requirement of Neovim 0.11

[nrupatunga]

[copilot.lua] Neovim 0.11+ will soon be required. Please upgrade your Neovim version if you wish to keep using this plugin.

Any reason in future you do not support 0.10?

This would be a pain because, other plugins has issues while moving to 0.11

There are some failing tests in 0.10.4 at this time and my guess is that it will only get worst.
I unfortunately do not have the bandwidth to go back and forth between versions to ensure the code works with older versions.
I would be happy to keep official 0.10 support if someone were to take on that maintenance though.
