[Bug] g.extension fails to install

[dhdeangelis]

Describe the bug

g.extension fails to install an extension. It reports an error seemingly attempting to read a non-existing file.

To reproduce

1. Go to 'Install extension from addons'
2. Select an extension, in this example 'r.area'
3. See error

> g.extension extension=r.area operation=add

Note that "r.area.md" is not present in "/usr/local/grass85/docs/mkdocs/source" nor in the local .grass8 folder.

Expected behavior

Addon installs correctly in local (user space) directory for addons.

Additional context

I have other 3 addons installed with a previous GRASS installation. These are correctly installed locally in .grass8:

> echo $GRASS_ADDON_BASE
/home/hernan/.grass8/addons

If we look at the CI logs of grass-addons (and even locally), every single addons (maybe with some exceptions) show this, but doesn't make the build fail.

[dhdeangelis]

It is failing in my case. Last time I installed addons was on 9th February and worked ok then.Now I cannot even reinstall the existing ones, failing on same issue.

[dhdeangelis]

I have now deleted my local .grass8 folder and /usr/local/grass85, and then rebuilt GRASS using the latest (938b9ad) main. The problem persists.

[veroandreo]

It seems to be searching for the documentation as md files, which for addons do not exist yet. And in dev, it changed during the past week or so.

[petrasovaa]

I runs for me locally, we tried to address it at least in a temporary way before the transition is complete. Try to use prefix and see if that changes anything.

Thank you @petrasovaa , but it does not change things for me:

Any chance you could test #5141 ?

[dhdeangelis]

It works fine. Thank you!
