Bogdan Chadkin b3c87af7c1 Migrate to pnpm for package management (#641) ...

- setup corepack for pnpm and forbid yarn usage with "engines" field
- converted yarn lockfile into pnpm lockfile with `pnpm import` command
- replaced yarn with pnpm in scripts and github actions, had to use
custom cache to support corepack

This PR is only migration. Will use new pnpm features in other PRs.

```diff
du -ckd1 node_modules (yarn)
- 1125032

du -ckd1 node_modules/.pnpm
+ 857456
```

Install time (including cache downloads) in github actions reduced from
42s to 23s
