(v3.6.10) - SB3 release and sphinx multiversion fix

[AlejandroCN7]

Description

This update makes Sinergym work with the latest SB3 release instead of the master branch, as they have included compatibility with gymnasium v1.0. They have not yet brought support for the latest versions of Torch and numpy v2.0. However, these updates will come in the future (we decided to delay the update of these packages in order to keep SB3 compatible with Sinergym).
On the other hand, this update includes some minor changes to the tool. The sphinx-multiversion issue has been fixed so that the documentation works again. In addition, a bug with package detection has been fixed so that SB3 tests can be relaunched normally. For more information visit the changelog.
