Port `brew --version` to Bash to speed it up. While we're here: - remove (now) unused `Tap` Git methods - use `--quiet` instead of `-q` to be more verbose Benchmarks: ``` $ hyperfine --min-runs=3 --warmup=2 "git checkout origin/master; brew --version" "git checkout speedup_brew_version; brew --version" Benchmark #1: git checkout origin/master; brew --version Time (mean ± σ): 2.083 s ± 0.004 s [User: 396.8 ms, System: 597.2 ms] Range (min … max): 2.080 s … 2.088 s 3 runs Benchmark #2: git checkout speedup_brew_version; brew --version Time (mean ± σ): 847.9 ms ± 35.2 ms [User: 100.0 ms, System: 247.9 ms] Range (min … max): 824.1 ms … 888.3 ms 3 runs Summary 'git checkout speedup_brew_version; brew --version' ran 2.46 ± 0.10 times faster than 'git checkout origin/master; brew --version' ```
