Use latest-v1 tag for hermes-compiler instead of nightly

[cipolleschi]

Summary

• Hermes V1 is the default now, so we need to resolve to that, not to nightlies which points to legacy hermes
• Switch the postinstall script to use latest-v1 instead, which points to the correct latest release.

Changelog:

[General][Fixed] - Use latest-v1 tag for hermes-compiler instead of legacy hermes nightly tag

Test plan

Run yarn install from the repo root and verify that hermes-compiler resolves to the latest version published under the latest-v1 tag.
