Update st2_chg_ver_for_st2.sh to use double quotes

[blag]

GHA CI is failing because our release scripts insert single quotes instead of double quotes:

sed -i -e "s/\(__version__ = \).*/\1'${VERSION}'/" ${INIT_FILE}
#                                   ^          ^

But black forces us to use double quotes:

================== black-check ====================

# st2 components
===========================================================
Running black on st2actions
===========================================================
would reformat /home/runner/work/st2/st2/st2actions/st2actions/__init__.py
Oh no! 💥 💔 💥
1 file would be reformatted, 59 files would be left unchanged.
make: *** [Makefile:372: .black-check] Error 1
Script done, file is typescript
Error: Process completed with exit code 2.

Running black manually:

This PR updates our release scripts to use double quotes, and updates the detection regex to allow for either single quotes or double quotes, just in case it is used against an older branch or fork of the st2 codebase.

Apologies for the gnarly branch name.

The corresponding PR to fix the existing code in the st2 codebase is StackStorm/st2#5299.

I think this can be merged - just been missed.
