Add this view for seeing new releases

[simonw]

CREATE VIEW recent_releases AS select
  json_object("label", repos.full_name, "href", repos.html_url) as repo,
  json_object(
    "href",
    releases.html_url,
    "label",
    releases.name
  ) as release,
  substr(releases.published_at, 0, 11) as date,
  releases.body as body_markdown,
  releases.published_at
from
  releases
  join repos on repos.id = releases.repo
order by
  releases.published_at desc

Better version (since this also includes JSON array of repository topics):

CREATE VIEW recent_releases AS select
  repos.rowid as rowid,
  json_object("label", repos.full_name, "href", repos.html_url) as repo,
  json_object(
    "href",
    releases.html_url,
    "label",
    releases.name
  ) as release,
  substr(releases.published_at, 0, 11) as date,
  releases.body as body_markdown,
  releases.published_at,
  coalesce(repos.topics, '[]') as topics
from
  releases
  join repos on repos.id = releases.repo
order by
  releases.published_at desc

That repos.rowid as rowid bit is necessary because otherwise clicking on a link in facet-by-topic doesn't return any results.

swarm-to-sqlite has an example of adding views here: https://github.com/dogsheep/swarm-to-sqlite/blob/f2c89dd613fb8a7f14e5267ccc2145463b996190/swarm_to_sqlite/utils.py#L141

I think that approach can be approved by first checking if the view exists, then dropping it, then recreating it. Could even try to see if the view exists and matches what we were going to set it to and do nothing if that is the case.

Blocked on #37

Without the rowid column facet by topics breaks: https://github-to-sqlite.dogsheep.net/github/recent_releases?_facet=repo&_facet_array=topics&topics__arraycontains=datasette-io

Faceting works now: https://github-to-sqlite.dogsheep.net/github/recent_releases?_facet_array=topics&topics__arraycontains=datasette-io&topics__arraycontains=sqlite&_facet=repo#facet-repo
