Subject: [PATCH] Use shell parameter expansion to make getting source path
 work in non-bash shells (#24598)

Currently `BASH_SOURCE[0]` was used, which is only available on bash.

I changed it to `${BASH_SOURCE:-$0}` which is supported by at least
bash, zsh and dash, as explained by
[https://stackoverflow.com/a/68359914/9028340](https://stackoverflow.com/a/68359914/9028340)

It uses shell parameter expansion

https://www.gnu.org/software/bash/manual/html_node/Shell-Parameter-Expansion.html

https://zsh.sourceforge.io/Doc/Release/Expansion.html#Parameter-Expansion

Addresses #17392
