fix: no longer leaking one buffer previewer in some occasions

[Conni2461]

And some other small things i noticed in the past week:

• fix docgen formatting
• fix in_fast_even when overriding file_maker
• fix filtering for space in keymaps with fzy (close Telescope keymaps broken for comma #658)
• remove count of files ignored by file_ignore_patterns (fix file_ignore_patterns not showing the correct number of results #247)
• don't write to invalid prompt (fix Errors while executing basic commands in latest neovim v0.5.0-dev+1140-g097ec71bd #640)

Docgen CI deleted everything because tree-sitter-lua wasn't bumped yet :| https://github.com/Conni2461/telescope.nvim/runs/2133421164?check_suite_focus=true

I believe this is due to neovim needing to be built with treesitter 19.x. They just released an update for nvim-treesitter. I dont think tree-sitter-lua needs to be bumped in this case. Not sure the environment that is building the nightly.

nvim-treesitter/nvim-treesitter#1000

[Conni2461]

The last nightly was build with 0.19.x so only ABI 13 is valid. docgen and the used grammar for docgen tree-sitter-lua is still build with 0.18.x. TJ does the bump to 0.19.x here: tjdevries/tree-sitter-lua#15

This is unrelated to nvim-treesitter because nvim-treesitter ships a different grammar.

Okay lot of fixes here :) Its done so someone should take a quick look at it and after that can merge it.

Docgen also works again 🎉
