ghostty: remove terminfo

[rrotter]

Ghostty always exports TERMINFO=/Applications/Ghostty.app/Contents/Resources/terminfo
This feature cannot be turned off in the Ghostty config.

Per macOS Sierra man terminfo:

If the environment variable TERMINFO is set, it is interpreted as the pathname of a
directory containing the compiled description you are working on. Only that directory
is searched.

IOW, linking from ~/.terminfo is redundant. These files can never be evaluated unless the user intentionally unsets $TERMINFO at runtime. Also, the iterm2 and kitty casks are doing fine without similar links.

Important: Do not tick a checkbox if you haven’t performed its action. Honesty is indispensable for a smooth review process.

In the following questions <cask> is the token of the cask you're submitting.

After making any changes to a cask, existing or new, verify:

• The submission is for a stable version or documented exception.
• brew audit --cask --online <cask> is error-free.
• brew style --fix <cask> reports no offenses.

Additionally, if adding a new cask:

n/a

• Named the cask according to the token reference.
• Checked the cask was not already refused (add your cask's name to the end of the search field).
• brew audit --cask --new <cask> worked successfully.
• HOMEBREW_NO_INSTALL_FROM_API=1 brew install --cask <cask> worked successfully.
• brew uninstall --cask <cask> worked successfully.

Seems fine to me. Would like some maintainers who use Ghostty to weigh in before we merge.

Fine for me. This follows kitty as mentioned with being embedded in the application path.

The same changes should be made to ghostty@tip

[rrotter]

rebased, added same change to ghostty@tip

Thank you @rrotter
