DEP Require framework ^5.3

[emteknetnz]

Issue silverstripe/.github#357

Fixes https://github.com/silverstripe/silverstripe-graphql/actions/runs/12640442927/job/35285220759 which broke because was using framwork 5.2 instead of 5.3 because this line was different - 5.2 - 5.3

This PR is a little unusual because there's nothing in elemental 5.3 that strictly requires API in framework 5.3, it's just that requiring a later version of framework is the only way I can think of fixing this. It may make more a little clearer to keep the ^5.2 framework contraint and add a conflict for framework < 5.3 instead, let me know if you would prefer that and I'll update the PR.

Broken tests were:

That sounds nonsensical to me - just bumping the dep is much clearer.
