This PR:

* re-generates all the schema-derived files so that they reflect the
latest changes made to the schema;
* adds some notes in the CONTRIBUTING document about how to make a SSSOM
release, and in particular to remind the person doing the release that
schema-derived files must be re-generated before a release.

Update PyPI publish workflow trigger

Workflow now only runs when a release is published, removing the trigger for prereleased events.

Update generated SSSOM schema files (#388)

Last commit before #189!

This is the usual update with `make all` (generating all downstream
python files).

This is going to be the final model update before sssom 1.0.

Fix SSSOM Schema not having bijective prefix map (#302)

There are issues in mapping-commons/sssom-py#397
because the base schema does not have a valid prefix map - `dc` and
`dcterms` are both used as prefixes for the same URI prefix. This
happens because LinkML makes some inference about what needs to be there
- there are some assorted uses throughout the schema definition with
both DC and DCTERMS. This PR updates the schema to only use DCTERMS and
puts explicit entries for DCTERMS in the prefix map to address this. It
then regenerates the whole project.

Package context files through `make` (#289)

This enables packages that use `sssom-schema` as a dependency to use
context files within this package rather than doing a `wget` which is
not efficient.

This will be address :
mapping-commons/sssom-py#375 via
mapping-commons/sssom-py#382
