1. Speed up the Tap#formula_files method …

   We already know that the directory and files are going to be formula files if they are ruby files
   so that's all we really need to check for here. The other change is to use `File.extname` instead
   of `Pathname#extname` which we assume is faster because it doesn't use the monkey-patched version
   that handles some additional extension types with multiple periods.
   
   ```
   $ hyperfine --parameter-list branch master,speed-up-loading-cask-and-formula-file-names --warmup 5 --setup 'git switch {branch}' 'brew cat gimp'
   Benchmark 1: brew cat gimp (branch = master)
     Time (mean ± σ):      2.109 s ±  0.010 s    [User: 1.349 s, System: 0.726 s]
     Range (min … max):    2.097 s …  2.128 s    10 runs
   
   Benchmark 2: brew cat gimp (branch = speed-up-loading-cask-and-formula-file-names)
     Time (mean ± σ):      1.795 s ±  0.011 s    [User: 1.061 s, System: 0.702 s]
     Range (min … max):    1.777 s …  1.813 s    10 runs
   
   Summary
     brew cat gimp (branch = speed-up-loading-cask-and-formula-file-names) ran
       1.17 ± 0.01 times faster than brew cat gimp (branch = master)
   ```
