Docs: create simple table with all terms as a searchable widget

[matentzn]

At biocuration, the conversation came up multiple times about the need of having a simple table with all the terms in the ontology. This could be delivered as part of the release process.

@lubianat was suggesting something as simple as:

1. four column table: ,"ID", "label", "definition", "category".
2. Search box for full text search with life subsetting like https://obofoundry.org/
3. "category" column can be configured using a specific annotation property, like biolink:category or similar

I cant stem this right now, but if more than 4 different people want this, I will get it done.

Thanks for the ticket, I'd love to see that. "Category" would already be a plus; I'd also say that having the aliases it could be good to improve searchability too
