This switches Alacritty's default configuration format from yaml to
toml. While yaml is still supported, it is done by converting it to toml
and should be removed entirely in the future.
All existing features were persisted based on my testing. Behavior
should not change much, though `--option` might have slightly different
behavior since the entire line is not interpreted as one line of toml.
A new `alacritty migrate` subcommand has been added which allows
automatic migration from yaml to toml. This also could be used as a
facility to automatically fix configuration file changes in the future.
Closes#6592.
This rewrites the existing manpages to use the `scdoc` format, making it
simpler to read and edit the manpages without intricate roff knowledge.
Some minor changes to the manpages were made in the process, mostly
focusing on correcting some of the wording. The list of maintainers has
also changed to ensure people not involved in the project anymore aren't
unnecessarily contacted for support.
