Documentation is outdated due to a build error

[M0NsTeRRR]

Hello,

Documentation hosted on RTD is outdated, there is an issue when building the documentation

https://readthedocs.org/projects/napalm/builds

Last successfull operation was 7 months ago

[M0NsTeRRR]

We should have a failure notification from RTD and it shoulds notify somewhere to prevents it again.
Linked to #1697

Read the docs changed things...

We are announcing the deprecation of build.image config key in favor of build.os. Read the Docs will 
start requiring a build.os config key for all projects in order to build documentation successfully. We 
will start failing builds for projects not using “build.os” in their config file on October 16, 2023.

The error is due to the missing build.os.

Yes I was creating the PR about it :)

Hmhm, it didn't trigger a rebuild on the RTD site. Is the webhook still configured? I think there might be another issue. The last build was 5 months ago, but you've pushed to develop many times since then.

I will need @mirceaulinic to look at it (as I don't have access on the read-the-docs side). GitHub webhooks is stating a 400 error.

I suspect readthedocs changed things / broke things on their side.

Documentation build is now fixed. If we intend to have documentation for both versions 5.X and 4.X, we need to port changes similar to what @mirceaulinic did for the master branch. Otherwise, we can consider closing the issue.
