- tslib 2.4.0 is forward and backward-compatible with older and newer
Node exports mechanisms, so the Node 17 error should no longer be
present
- it has the older `./` and the newer `./*` in its package exports,
which should allow for `package.json` to be read in both older and
newer implementations
- this allows us to remove the extra dep on `@yarn-tool/resolve-package`
as well
- other than less unnecessary deps being good,
`@yarn-tool/resolve-package` is also a not well-documented package
with very few users, which does not make for a good security posture
for rpt2 (which has historically prioritized supply chain security
in other issues around deps) or, in particular, its consumers, which
there are very many of (in contrast with `@yarn-tool`)
- per my issue comment, we could also have avoided the extra dep prior
to the tslib upgrade by resolving to absolute paths, as Node only
does a "weak" encapsulation of relative imports
- test: add a small unit test for tslib.ts to ensure that this method
works and passes on different Node versions in CI
- more a smoke test that it runs at all, the testing is additional
and a bit duplicative of the source tbh
