Switch to pnpm

	installation time	node_modules size
NPM i	10.79s	451M
PNPM	2.49s	342M

It's okay that size job is failing. It's because it can't install dependencies on master without pnpm-lock.yml

I think we can use https://nodejs.org/api/corepack.html for activate pnpm
corepack pnpm install

[akellbl4]

Hm, I think its too early for corepack. It was introduced in v18 and it's experimental.
But worth considering when we move towards update to node18

UPD: Oh, I'm wrong it's available in v16.
