build: update pnpm to v11 (#37591)

Update to https://github.com/pnpm/pnpm/releases/tag/v11.0.0

- move all pnpm settings to `pnpm-workspace.yaml`, pnpm v11 only reads
that file
- drop redundant or no-op settings
- disable `strictDepBuilds` to avoid having to manually specify deps
with build scripts, this is equivalent to v10 where it will not execute
and warn.
- add workarounds for https://github.com/SukkaW/nolyfill/issues/119
- remove dead eslintrc entry
