chore: require pnpm 10

Bump engines.pnpm to ^10 (pnpm 9 reached EOL) and align CI plumbing
with the new constraint:

- Add root .npmrc with `public-hoist-pattern[]=*eslint*` and `*prettier*`
  so transitive plugins of @theguild/{prettier,eslint}-config remain
  resolvable from the workspace root after pnpm 10's hoist defaults
  changed (otherwise `prettier -c .` errors with
  "Cannot find package 'prettier-plugin-sh'").
- Rewrite the pnpm-version step in setup-node/action.yml so it honors
  the `packageManagerVersion` input first, falls back to a sane default,
  and fixes the broken `if [ ! -z {{inputs.packageManager}} ]` shell
  (missing `$`, was always truthy).
- Pin pnpm to 10.17.1 explicitly via packageManagerVersion at every
  setup-node call site in ci.yml and publish.yml.

No root `packageManager` field is added: yarn 1 (still the system yarn
on GitHub runners) refuses to coexist with a non-yarn value, which
trips the CLI init tests' `yarn link @graphprotocol/graph-cli` step.
