[dependabot]

Bumps ramsey/composer-install from 3.2.1 to 4.0.0.

Release notes

Sourced from ramsey/composer-install's releases.

4.0.0

What's Changed

• chore: Bump actions/cache from 4.2.4 to 5.0.3 by @​dependabot[bot] in ramsey/composer-install#278

  This necessitates a new major version because actions/cache v5 runs on the Node.js 24 runtime and requires a minimum Actions Runner version of 2.327.1. This is a breaking change for anyone using self-hosted runners.
