Add .helix to .gitignore
helix can use project specific configuration in the .helix
directory under
the project root. For gst-rs development, this can be used to select a group of
features:
.helix/languages.toml:
[language-server.rust-analyzer.config]
cargo = { features = ["v1_26"] }
It can also be used to configure debugging targets, thought debugging experience with helix is lacking currently.
