feat(telecope): set show_untracked by default

[pschmitt]

Description

• add the ability to display untracked files by default when invoking find_project_files
• can be turned off by setting the show_untracked to false.

How Has This Been Tested?

-- show untracked files
require('lvim.core.telescope.custom-finders').find_project_files()

-- skip untracked files
require('lvim.core.telescope.custom-finders').find_project_files({show_untracked = false})

I'm in favor of making this a default behavior actually! in that case, we'd have it set in telescope's config table, and it could still be overridden.

I agree this should be the default. I'm actually pretty sure it used to be for the default <space>-f "find files" keybinding but it was changed at some point.

LGTM 🚀
