Pull request overview

Updates try-repo to generate and display a prek.toml configuration instead of emitting a YAML snippet, aligning the command’s behavior with the Rust prek TOML config format.

Changes:

Switch try-repo config generation from YAML string templating to TOML generation via toml_edit.
Write the generated config to prek.toml (in the temp dir) and print it with a trailing newline for cleaner output.
Update integration test snapshots to expect TOML output ([[repos]], hooks = [...]).
