brew doctor output

> brew doctor
Your system is ready to brew.

Verification

• My "brew doctor output" above says Your system is ready to brew. and am still able to reproduce my issue.
• I ran brew update twice and am still able to reproduce my issue.
• This issue's title and/or description do not reference a single formula e.g. brew install wget. If they do, open an issue at https://github.com/Homebrew/homebrew-core/issues/new/choose instead.

What were you trying to do (and why)?

• Tried to install [email protected]. Alias for this exists at https://github.com/Homebrew/homebrew-core/blob/a44bd8e98ffee5f800a1c5c94532892ffdcfe822/Aliases/go%401.22
• Checked other Formulas installation using Aliases (for example [email protected])

What happened (include all command output)?

No available formula with the name ... errors. Outputs examples:

❯ brew info [email protected]
Error: No available formula with the name "[email protected]". Did you mean [email protected], [email protected], [email protected], [email protected], [email protected] or [email protected]?
Command /opt/homebrew/bin/original-brew info [email protected] failed!
❯ brew install [email protected]
Warning: No available formula with the name "[email protected]". Did you mean [email protected], [email protected], [email protected], [email protected], [email protected] or [email protected]?

To install [email protected] ✔, run:
  brew install [email protected] ✔

❯ brew info [email protected]
Error: No available formula with the name "[email protected]". Did you mean [email protected]?

What did you expect to happen?

Expected that formulas to be installed, as we have aliases for them.

Noticed that it happens if homebrew/cask tap is untapped (default behavior for brew > 4.0.0). If we have homebrew/cask tap - Aliases work as expected.

Step-by-step reproduction instructions (by running brew commands)

1. Ensure that `homebrew/cask` tap is not added with `brew tap` command (shouldn't be added by default).
2. Try to use any Formula Alias, for example `brew install [email protected]`
