Feature request: make it easier to browse/search old articles

[maelle]

Today while looking for @hfrick's post https://www.tidyverse.org/blog/2022/02/upkeep-testthat-3/ I first clicked on the categories "programming" and "deep-dive". I feel it'd be easier to find if there were search on the blog, or a more findable list of tags (I would have clicked on "testthat").
Thanks a lot for the resources in any case!

Just adding my voice that this would have come in handy several times for me too. I went to this github page and used github search to find the keyword I was looking for in the articles.
