release: 4.5.1 (#5354)

* chore(release): bump version to 4.5.1

* chore: bump helm chart

* chore: update CHANGELOG

* Revert "chore: bump helm chart"

This reverts commit 703b03b665.

* chore: bump helm chart to 3.0.0

* revert: remove bad change to manifes.json icon

* fix(ci): add package.json.version to code cachekey

Before this, creating a release sometimes prevented vscode from
rebuilding and using the cache instead. Now we use the
package.json.version in the cache key to "bust" the cache if the
package.json version is updated (aka a release).

Fixes #5316

* Update .github/workflows/ci.yaml
