feat(install)!: add explicit path field to parser info (#6476)

Problem: Using `url` for both remote repo and local path complicates the
code.

Solution: Add `path` field that overrides `url` and bypasses
git-specific manipulations, i.e., the contents of the `path` are used
as-is (no git repo needed).

This means `:TSUpdate` will skip such parsers; use `:TSInstall!` instead
after making local changes.
