Swap in PageFind in place of Google Custom Search

[cjyabraham]

From cncf/cncf.io#836:

GCS doesn't seem to produce very good search results on small sites. It'd be better to remove our reliance on Google as well. Instead we can use PageFind, which is an open source local search for static sites.

In addition to installing PageFind, this PR changes the packaging and build of the site to be consistent with other CNCF subsites. It simplifies the build and removes the dependency on mage, go and docker. Also, it was the only way I could figure out how to get the site to work with PageFind. (Let me know if there are any objections to this change.) I've updated the instructions for how to run the site locally.

I am good with the PageFind changes. However

It simplifies the build and removes the dependency on mage, go and docker.

I like Mage and Docker setup as it enables people to test with the exact same version of Hugo.

For example, I have 0.11x of Hugo locally, but another person has 0.12x. Container build is helping with that consistency. It also helps as I manage various Hugo websites which use different versions of Hugo.

I am not a big fan of Mage, but containered build is nice.

What do you think?

Ok. I personally don't have much experience with Docker. Would you be able to adapt what I've got here to use it?

I'm basically trying to standardize the way all these CNCF subsites are built while also getting PageFind to work. I don't know of us ever having a problem in the past with different Hugo versions but we can use Docker if you think it's needed.

Any thoughts on this @aliok? Just to note, none of our other subsites (listed here) use docker in their build process. I don't get the sense that we're doing anything with Hugo that would produce different behavior under different versions.

@cjyabraham sorry I was on PTO last week and I will be unavailable this week for a business trip. I don't want to block this PR.

Let's merge and if Docker builds are really really needed, I can add support for that later on.

Sounds good @aliok . Thanks.
