[REFACTOR] Rename -core package to -common to remove a source of confusion

[Victor Schappert (vcschapp)]

Description

As discussed and agreed in the 2026-03-11 / CODING SESH 💻 meeting, this change renames the overture-schema-core package to overture-schema-common.

The purpose of this change is to eliminate a source of confusion caused by overloading the word "core":

• Since early days, the word "core" has been used in Overture to mean that part of the map and its schema that is of central importance and not peripheral.
• However, in the overture-schema-core package, the word "core" was being used in a different sense to mean basically shared types that are common to more than one theme schema.

This issue has produced real confusion and consumed many minutes of unproductive discussion in meetings. It is hoped this change will eliminate the confusion going forward.

Reviewer Notes

• Added Adam Lastowka (@Rachmanin0xFF) as a reviewer because this change may potentially break usage of the Pydantic schema in the data pipeline and the team should have a heads up there.

For the failing CI check: CodeArtifact has published versions through 1.1.1dev3 (Stephen Epps (@stepps00) and I figured this out while dealing with the staging merge), so the version will need to be bumped past that to succeed.
