Less log spam (non git worktrees; saving with no LSP) (#29557)

- See: https://github.com/zed-industries/zed/discussions/29541
- `failed to get git blame data:` occurred whenever opening a file that
does not have git blame data and with `git.inline_blame.enabled` = true
(the default). Notably this would be triggered whenever you opened your
settings or keymap (unless ~/.config/zed was git managed).
- `No language server found to format buffer` triggered whenever you
saved a buffer with `format_on_save` (the default for most languages)
but had no LSP configured for this file type (e.g. Plain Text).


Release Notes:

- N/A
