Description

Fixes #2476

I bumped versions of some dependencies.

• Old Jinja2 doesn't work with new markupsafe, so I upgraded Jinja2.
• Old Flask doesn't work with new Jinja2, so I upgraded Flask.
• Flask requires minimal versions of click, itsdangerous and werkzeug, so I upgraded them.

Upgrades unrelated to markupsafe to make examples work:

• protobuf was pinned to a conflicted version because of some transitive dependency changed:

The conflict is caused by:
    The user requested protobuf==3.18.3
    googleapis-common-protos 1.52.0 depends on protobuf>=3.6.0
    opentelemetry-proto 1.20.0 depends on protobuf<5.0 and >=3.19

• wrapt < 1.14 is incompatible with Python 3.11 (https://github.com/GrahamDumpleton/wrapt/blob/develop/docs/changes.rst#version-1140), I upgraded them to be able to run examples.

We could at least have a CI action to install these example requirements file to check if they're not outdated.
