build(vim-patch.sh): don't ignore changes to version*.txt (#29425)
Suggest adding them to news.txt instead.

Also don't ignore changes to intro.txt and sponsor.txt, as they don't
change much these days, and it's necessary to consider whether to
include their changes in Nvim's intro.txt.

Instructions:
To port one of the above patches to Neovim, execute this script with the patch revision as argument and follow the instructions, e.g.
'${BASENAME} -p v8.1.1234', or '${BASENAME} -P v8.1.1234'
NOTE: Please port the _oldest_ patch if you possibly can.
You can use '${BASENAME} -l path/to/file' to see what patches are missing for a file.
