Build housekeeping for December

[smallsaucepan]

Doing chores 🧹

• Updated build dependencies: tape, tsx, tsup, tslib, babel, rollup, monorepolint, and eslint.
• Removed a monorepolint rule that wasn't adding much value. Enforcing rollup version in only one package.
• eslint largely migrated automatically. Had to broaden some rule disabling for types.ts and test.ts. Unsure though if that was a config migration issue or eslint getting harder to please in its old age.

This probably isn't going to pass CI until we drop building on node 16 - eslint/eslint#18851 (comment)

[smallsaucepan]

Made a meal of this in my fork. Will start again.

There was a conflict between eslint and the node 16 build. Now that we've dropped 16 from CI these changes pass. Ready for review!

Generally this looks okay to me. You also eradicated 'ts-node' as a dev dependency from the top level package.json, assumedly its behavior is replaced with tsx?

I don't know if the monorepolint piece has been superseded by some other actions/library? i.e. is there any programmatic enforcement of consistency between packages?

[smallsaucepan]

Thanks for that. Yes, I'm going to guess we left ts-node in to be safe when revamping the build last year. Couldn't find any remaining references to it now though.

don't know if the monorepolint piece has been superseded

On the whole monorepolint still runs - haven't changed that. All I removed was a rule that verified the rollup version in a single package. The rule wasn't adding any value except making someone update the version in two places should they upgrade rollup.

MRL is still making sure we use the same version of typescript, etc in all packages.
