impl: update icons to match the new branding (#555)

* impl: update icons to match the new branding

* fix: eap build is no longer available for verification

In the previous PR 2025.2 EAP build was available on the default repositories,
it no longer seems the case. Additionally, I've configured the verification
phase to use the latest available 2024.3 patch (6 patches available)

* chore: next version is 2.21.0
