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.

Change slot_uri for literal (#357)

Made a mistake here #356 Thanks for catching @hrshdhgd

- [x] Moved `mkdocs-mermaid2-plugin = "^1.1.1"` as a dev dependency
 - [x] ran `poetry lock --no-update`

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#382
