Reword descriptions that are too long

[samford]

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:

• 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).
• Checked the cask is submitted to the correct repo.
• 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.

We're working on getting brew style working again (Homebrew/brew#17482) for some circumstances where it was broken (e.g., checking taps) and brew CI is surfacing some more issues in homebrew/cask. This PR rewords description values that are longer than 80 characters.

There are also some shellcheck issues to resolve in the workflows here but I'm going to create a separate PR for that, so we can easily revert it if it breaks something.
