Homebrew’s instructions to update Xcode CLT fail to address warning

homebrewxcode

Since Catalina, brew doctor has produced the message

Warning: A newer Command Line Tools release is available.

Following the subsequent instructions to

sudo rm -rf /Library/Developer/CommandLineTools
sudo xcode-select --install

has no effect.

How do I make sure that Homebrew recognizes that no newer version of the CLT are available?

This bug report, which is closed as expected behaviour, has this solution:

MikeMcQuaid: Run xcode-select --install. If that doesn't work check for Mojave system updates. If that doesn't work reboot your machine and try both again. If that doesn't work try to download and install the latest CLT from https://developer.apple.com/downloads/more/

From the discussion under it, it seems you need to have both Xcode's CLT and the /Library CLT.
