Change advertisement position in new pydata theme

[AdamRJensen]

Is your feature request related to a problem? Please describe.
With the new pydata theme implemented in #1173, the ads from readthedocs have become much more prominent. E.g., the main pvlib landing page in the latest version is dominated by the advertisement (see screenshot from a phone below):

Describe the solution you'd like
While there are good reasons for having the advertisement, I do not think that it should be the most dominant feature that greets users.

One solution would be to move the advertisement to the bottom of the page. Though I have not been able to determine if this is possible with the theme. Perhaps @choldgraf could add a comment on this?

I noticed that other sites using the template also feature the ad at the top on the mobile version, e.g., pydata theme, binder, and jupyterhub.

Additional context
I fully support changing to the new theme btw.

Of these options:

1. Pay readthedocs
2. Hack the theme
3. Build the docs in the ci, post to a github.io repository.
4. Live with the ads

I prefer 4, 1, 3, 2.

Would be nice if PVPMC could pay for rtd ad free hosting and, while we're at it, a domain name too. While the combined price of that is roughly $100 per year, I'm guessing the overhead in making that happen is on the order of $1000 per year, unfortunately. Maybe there's a more efficient path through numfocus or github sponsors.

I think that the right long-term solution is to make the sidebar collapsible when you're on mobile, rather than having it displayed at the top of the page. Agreed it is sub-optimal

Another option would be to move the advertisement to the right-hand side. This only would require a minor change of the sphinx settings and avoids the advertisement being placed at the top on smartphones.

In general the left-hand side of a webpage tends to get the most attention, so either way, I would favor moving the advertisement to the right.

ah I just realized that you could do this already with theme configuration, by following these instructions:

You should try putting the sidebar-ethical-ads snippet in the footer:

https://pydata-sphinx-theme.readthedocs.io/en/latest/user_guide/sections.html#the-footer

does that work?

@choldgraf I successfully moved the ad to the footer in #1359 and it worked like a charm!

I really think it's a win-win, it moves the advertisement to the bottom on smartphones and makes it less dominating in the browser version.

Would it make sense to make this the default for the theme?

[choldgraf]

well we probably don't want the advertisement in the footer on a full width, since it'd generally be hidden, but I think the "hidden sidebar" that I mentioned above is a reasonable compromise
