Fix bash indentation and trailing whitespaces

Some shell scripts had tabs indentation. Made it all four spaces.
Hope it's ok with spaces.

Some files had a trailing space in it. It was not useful and takes few bytes for
nothing.

I didn't delete everything.

You can find all tab indented lines with:

grep -rP '^\t' 2>/dev/null

And more trailing space with:
grep -rP ' $' 2>/dev/null

 Previously, Docker images were community maintained, had their own repository and weren't official supported. We changed that with v5.4.0 during July 2023. Thanks to @promasu for all the work on the community images.
