Homebrew installer uses Python 2

[michaelblyons]

Describe the bug
The Homebrew installer for SSLyze depends on python@2, not Python 3.

See

• https://github.com/Homebrew/homebrew-core/blob/e38c893938957ae84cb3a7294845e2cf337e0923/Formula/sslyze.rb#L34
• https://github.com/Homebrew/linuxbrew-core/blob/966a6e1d8fb1932b7a8c3efbc6f175047cbf97ca/Formula/sslyze.rb#L34

To Reproduce
Steps to reproduce the behavior:

1. Install SSLyze using brew install sslyze.

2. Run the following command: brew deps sslyze.

3. See error:

   $ brew deps sslyze
   gdbm
   [email protected]
   python@2
   readline
   sqlite
   

Expected behavior
The python@2 line should be python. Python 2 is soon-to-be-unsupported. SSLyze seems to support Python 3, so the Homebrew package should use that instead.

Python environment (please complete the following information):

• OS: macOS Catalina
• Python version: 3.7.5

I did not realize that Homebrew/homebrew-core#45750 existed when I filed this. I'll watch that PR and close this issue when it's merged.

Things are a little hectic at Homebrew over the removal of Python 2 and the upgrade of Python 3.7 to 3.8. This has resulted in the opening, closing, and superseding of several PRs, but I think everything is resolved for SSLyze now with Homebrew/homebrew-core#47993
