fixes for docu, spelling, plus single elisp

spelling, whitespace, yaml indent
elisp fix for group

[jcs090218]

I have intentionally set those indentations. 🤔 Do you have the reason why?

1222203 is just style fix (no whitespace after an opening bracket)
6354116 is an indentation fix highlighted by yamllint "expected 10, found 8" which fixes consistency with "emacs-version:" indent as well, and looks correct to me per https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions

Caveat I haven't tested the yaml whitespace changes, but the whitespace defines the structure per https://docs.platform.sh/learn/overview/yaml/what-is-yaml.html https://stackoverflow.com/questions/42247535/yaml-how-many-spaces-per-indent
The other fixes may be higher priority, given I don't know the priority of the yaml.
