Plugin fails to enable on recent Python versions due to pkg_resources usage

[DonatoBD]

Description

The current implementation of both the tutor-contrib-limesurvey plugin and the LimeSurvey XBlock relies on pkg_resources from setuptools.
In recent Python versions (3.12+), pkg_resources has been deprecated and is no longer bundled with the standard library, which causes import errors when enabling the plugin.

As a result, the plugin cannot be enabled in modern Tutor environments running Python 3.12 or newer, and this breaks deployments that depend on it.

This is a similar problem to the one reported in Tutor core:
overhangio/tutor#966

Steps to Reproduce

1. Use a recent Tutor environment (Python ≥ 3.12).
2. Install and enable the tutor-contrib-limesurvey plugin
3. Run tutor instance
4. Observe the error indicating that pkg_resources cannot be imported.

Expected Behavior

The plugin should enable successfully without errors on recent Python versions.

Actual Behavior

Plugin fails to enable due to:

ModuleNotFoundError: No module named 'pkg_resources'

Impact

• This plugin is used by other clients, including Ceibal and UPM.
• This issue blocks deployment or upgrades using azimut because run Tutor on Python 3.12 for these clients, or requires removing these plugins in order to migrate them to Azimut
