fix: broken tests (mostly out of stuff being outdated) (#468)

* Update rebar3's releases.json per current results

* Up rebar3 test versions

* Retire windows-2019

* Add "support" to win25-vs2026 next to win25

windows-2025-vs2026 label was previously a beta testing
tag but is now the production default

* Fix rebar3 test releases.json

* Bump per CI results

* Fix per CI results (I checked in releases.json)

* Adapt to Ubuntu 26.04 (no -arm)

* Consider Ubuntu ARM variants in execution

* Typo

* Bump it to the minimum expect value

* Bump it to the minimum expect value

* Tweak ARM tests: drop windows-11

* Fix per prior test results

* Try testing OTP to update README

* Improve guarantees on the README (via tests)

* Improve guarantees on the README (via tests)

Trust tests in intervals (if first Ok and last Ok the middle Ok)

* Add further constraints for testing (per README)

* Remove moving-target test

This is prone to fail for an issue with OTP's main
branch but it shouldn't affect the action, so we
remove it

* Respect Hex's boundaries

* Make it consistent (no need for .0 in versioning)

* Restrict it a bit

We keep the README as-is, since there's nothing preventing us
from thinking it works as stated, but we move our tests forward

* Make it easier to follow

* Fix it per stalled CI

* Fix it: no macos-16; it's macos-26

* Deprecate macos-13

Per https://github.blog/changelog/2025-07-11-upcoming-changes-to-macos-hosted-runners-macos-latest-migration-and-xcode-support-policy-updates/#macos-13-is-closing-down

* Make ImageOS support more explicit

* Move forward
