Upgrade to Bash 5 in MacOS

I am a long time user of Zsh but I also use Bash now and then but mostly when running bash scripts. The other day when upgrading SdkMan it complained that I was using an old version of bash. I have to admit that I have used the default bash installation in MacOS. What I didn’t know was that Apple will not update Bash, because the latest version is licensed under GPLv3, which Apple cannot use.
