fix(build): non-git ("tarball") build fails #19448

Browse Source 
Problem:
Build fails without git or .git/.
ref #19289

Solution:
Fix the version generation logic.

Test cases:
If `git` is missing:
    -- Using NVIM_VERSION_MEDIUM: v0.8.0-dev
If `.git/` is missing:
    -- Git tag extraction failed:
       fatal: not a git repository (or any of the parent directories): .git
    -- Using NVIM_VERSION_MEDIUM: v0.8.0-dev
If `git describe` fails
    -- Git tag extraction failed:
       fatal: ...
    -- Using NVIM_VERSION_MEDIUM: v0.8.0-dev
