Comment:
Also: I added `texinfo` as a dependency of `octave` to close #50442.

It could be argued that it is an optional dependency (it's required only for the help system) but it's small compared to octave + all its dependencies that it doesn't seem out of reason to make it mandatory.

OTOH, the error when one tries to use help texinfo is very reasonable:
```
octave:1> help help
sh: 1: makeinfo: not found
sh: 1: makeinfo: not found
warning: help: Texinfo formatting filter exited abnormally; raw Texinfo source of help text follows...
'help' is a function from the file /usr/share/octave/9.1.0/m/help/help.m
```
in the sense that it's obvious what to do (assuming one has install-powers).

I'm fine either way, leaning slightly towards add the dependency (which I did in this PR).
