runtime(lua): update 'path' option in filetype plugin

Problem: Lua doesn't support importing module in path related to current
file like JS does (https://www.reddit.com/r/lua/comments/wi0bau/whats_the_correct_way_to_run_a_lua_file_that_uses/)
Solution: Remove `.` from Lua buffer-local option `'path'`

closes: #17267
