Add ability to customize documentation pages using jinja templates (#333

)

Resolves #332 

This PR added in the relevant/necessary base jinja templates (as is)
from the linkml library:
https://github.com/linkml/linkml/tree/main/linkml/generators/docgen in a
folder called `src/doc-templates`. Now the jinja templates can be edited
here, in order to customize the class/slot/index, etc. documentation
pages to look like how we want them to look. The downstream makefile
target which uses linkml `gen-doc` is `make gendoc` and that has been
updated too.

- [ ] `docs/` have been added/updated if necessary
- [x] `make test` has been run locally
- [ ] tests have been added/updated (if applicable)
- [ ]
[CHANGELOG.md](https://github.com/mapping-commons/sssom/blob/master/CHANGELOG.md)
has been updated.
