fix(docs): add dynamic versioning to docs build

[kenibrewer]

Description

This change will ensure that RTD docs in the latest section will more correctly display a version such as 1.0.0.post7.dev0+g29045e8 when the main branch contains 7 un-released commits instead of continuing to display 1.0.0.

This introduces the dunamai docs dependency which is already an indirect dependency for our build process. poetry-dynamic-versioning uses dunamai to calculate the appropriate version strings.

Closes #352
