fastapi example missing dependency

[skoblenick]

Describe the Bug

trying to run the fastapi example results in an error due to a missing dependency:

    assert jinja2 is not None, "jinja2 must be installed to use Jinja2Templates"
AssertionError: jinja2 must be installed to use Jinja2Templates

adding the jinja2 via poetry

poetry add jinja2

fixes the issue.
