cask "thunderbird" points to an unstable release

Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match / SHA256 mismatch error (do not open an issue before trying to open a PR to fix first).

Description of issue

i apologize in advance if this is the wrong format or place for this! Would be happy to give more details or submit somewhere else.

Problem:
brew install --cask thunderbird installs the unstable monthly release and not the expected stable release.
Currently the "thunderbird" cask installs the monthly 133 and "thunderbird@esr" installs the stable version 128.5.0esr.

On startup thunderbird version 133 (current default) gives the following error message:
"this is an unsupported version of Thunderbird!!
Thunderbird monthly releases are not considered stable for general use.
Use at your own risk, this build is the same quality as Thunderbird Beta.
We recommend downloading the latest stable version of Thunderbird."

Expected behavior:
That "brew install --cask thunderbird" installs the latest "esr"/stable release.

Solution:
Rename current "thunderbird" > "thunderbird@monthly" (or similar) and rename "thunderbird@esr" > "thunderbird"
The "default" version (without @) should arguably be the "esr"/stable release and if one wants features from the monthly unstable release those should be under thunderbird@monthly or thunderbird@beta etc.
