Commit Message

Allow choosing custom versions of python for graders (#92)

## Motivation
* Sets us up for supporting Java (notably this DOES NOT add official
Java support)
* Allows us to offer higher versions of python, without breaking
backwards compatibility with graders relying on python 3.10 behavior

This PR also does not add a warning banner if an assignment is using a
deprecated version of a language, in order to reduce the already large
and complex diff. This would be better as a "good first issue".

## Implementation
This adds a new model, `Language`, which stores information about the
language, binary path, and more. The field `Assignment.language` has
been moved inside said model. All the information about the specific
language is stored in a dictionary called `info`.

The `info` dictionary must contain a `version` key that is sortable. For
the `python` grader language, it must also contain the key `python3`
which has the absolute path to a python executable.
The addition of another language to Tin can then consist of simply
adding other keys to the `info` dictionary as needed.

> [!IMPORTANT]
> Custom migrations were written in order to facilitate this transition
with minimal problems.

The rest is just some restructuring:
* Changes the `run_submission` task to use the assignments executable
* Filters the edit assignment/create venv to only show non-deprecated
language options.
* Changes the `create_venv` task to use the correct executable
