release: 4.5.0 (#5308)

* chore(release): bump version to 4.5.0

* chore: update CHANGELOG

* chore: bump chart version

* docs: update MAINTAINING

* fix: add VSCODE_DEV=1 to e2e script

I'm not sure what changed in the latest version but without setting
VSCODE_DEV=1, code-server won't load. This fixes that.

* Revert "fix: add VSCODE_DEV=1 to e2e script"

This reverts commit 58c4826af8.

* fix: try setting VSCODE_DEV=1

* Revert "fix: try setting VSCODE_DEV=1"

This reverts commit 902f5f2f30.

* refactor: remove version check e2e test

I am not sure why this is passing locally and failing CI. I need to
further investigate this since it fails depending on where you test.
