website/**/es: Kill es translation for website

[bofh]

Summary

It looks like that there is very little interest from the Spanish
developers about FreeBSD as there has not been any single commit on this
apart from the obvious ones:
https://cgit.freebsd.org/doc/log/website/content/es

Additionally our index page also do not point to the Spanish
translations although they do about de, fr, ja, zh-cn and zh-tw.

So I think it's better to kill it rather than serving old outdated
information. If there are more interests from the community we will
reconsider adding or resurrecting this.

Just to clarify this do not delete the es documentation and also have no
such intention to delete. The documentation will remain as is.

I would like to start with this at some point, but I didn't have time yet.
I'm considering this a small nudge so I can start the task, but I will not oppose if you think we should delete it for now.

I would like to hear from @carlavilla too.

I had the notion that @fernape was from Italy. I hope that you will work on it and fix those. But it's too much work to maintain a translation of the website specially keeping it upto date. I believe you will maybe do it one time to sync it with the latest en but will you be able to maintain it regularly? In FreeBSD world there is always something happening. :)

If you can be my guest.

LGTM.

If at some point we deem it necessary, we can translate the website.

[carlavilla]

Go ahead, but in the future, with the new design, I’ll translate the website :)
