Don't remove the lychee config file

[dmathieu]

This fixes the removal of unncessary files, which currently removes too much, as it removes the config file. But also the lychee-bin and lychee-lib files:

$ touch lychee-bin; git status; rm -f lychee*!(lychee-bin|lychee-lib); git status
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
(use "git add ..." to include in what will be committed)
lychee-bin

nothing added to commit but untracked files present (use "git add" to track)
On branch main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
(use "git add/rm ..." to update what will be committed)
(use "git restore ..." to discard changes in working directory)
deleted: lychee.toml

no changes added to commit (use "git add" and/or "git commit -a")

Here, we can see that not only the lychee-bin file has been removed, but the lychee.toml file has been removed too (which prevents the action from running properly).

Now, with my new command:

touch lychee-bin; touch lychee-bar; git status; rm -f lychee!(-bin|-lib|*.toml); git status
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
(use "git add ..." to include in what will be committed)
lychee-bin
lychee-bar

nothing added to commit but untracked files present (use "git add" to track)
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
(use "git add ..." to include in what will be committed)
lychee-bin

nothing added to commit but untracked files present (use "git add" to track)

Note: I tried running this as rm -f lychee!(lychee-bin|lychee-lib|*.toml), but for some reason, the bin and lib files were still being deleted.

Thanks for the fix!
