Set different minimum version requirement for Lesson Tour if needed

[Imran92]

We currently have the same minimum version requirement for Course and Lesson tours. In case we require a separate version number, update it before the release.

Here's the code where the version update should go https://github.com/Automattic/sensei/pull/7519/files#diff-8593e0545da650b133ab8c138edb081d9670c66a858e4d746683891b31bad3faR74.
