release: 4.9.0 (#5772)

* wip: changelog

* fixup

* fix: add +x to product.json in build-vscode

While testing a pre-release, there seems to be a bug with the file
permissions for `product.json`. Adding `chmod +x` to see if that fixes
it.

* chore: increase timeout

* fix: keep product.json file permissions in release

When we added the change to modify the `package.json` version using `mv`
and `jq` we didn't account for lost file permissions.

This caused a bug only happening in CI.

This should fix it by giving it 755 via `chmod`.
