Update workflows using v2 of actions/cache

[elycheea]

The problem

Workflows using v1-2 of actions/cache will fail after v1-2 are deprecated in February 1, 2025¹.

The solution

Update your workflows to begin using a supported version of actions/cache, and upgrade your actions or other products that depend on the @actions/cache package to 4.0.0 or above.

Supported versions

actions/cache:

• actions/cache@v4
• actions/cache@v3
• actions/cache@v4.2.0
• actions/cache@v3.4.0

Cached entries within their retention period will remain accessible from the UI or REST API regardless of the version used to upload.

Acceptance criteria

• Update ci.yml from v2 to v4 or higher
• Update update-example-gallery to v4 commit hash
