Bump a bunch of versions

[bollwyvl]

Hey folks! I tried getting the local dev machinery set up, but ran into a bunch of issues... in looking into said issues, I found some of them had been fixed by newer versions.

This PR just gets to a happier dependency/setup place so that subsequent PRs aren't quite as involved.

Changes

• bump up blockly to 9
  • uses much improved, first-class upstream typings, less (Partial)JSONObject
  • add name to theme
• bump many dev dependencies, notably:
  • @jupyterlab/builder to avoid verdaccio, etc.
  • lerna (5.x not supported anymore)
  • use jlpm all over
    • remove extra yarn
    • remove extra run in commands
    • add yarn-deduplicate
  • typescript just because
  • update tsconfigs a bit
    • target: es2018
    • use references for single watch
• bump up binder python
  • default's 3.10 anyway, now
• pin jupyterlite==0.1.0b18 (it's going to get a bit bumpy for a sec)

Thank you so much, @bollwyvl!

Well, I don't know what releaser is going on about, or why it's npm packing a private package. But otherwise, this seems pretty ready to go to get on to other work.

Yes, I looked a little bit at the PR, and it looks good. Thanks, @bollwyvl.
Don't worry about the releaser; I'll take a look at that.
