[DEVX-5757] Release Terminus 4.1.0 (#2737)

* Update version to 4.1.0 for release

* Fix changelog format to match existing convention (remove square brackets)

* Add complete changelog entries for 4.1.0 release

Include all changes since 4.0.3:
- Add PHP runtime generation and version to env:list (#2729, #2732)
- Fix workflow:wait timeout to use warnings instead of errors (#2724)
- Preserve consolidation filter hook when running composer update (#2728)

* Remove internal build script change from changelog

PR #2728 (consolidation filter hook) is an internal build script change
not relevant to customers, so removing from changelog per documentation.
