ref: Make note about supported versions more generic (#14364)

We have an info note on some Python integration pages that suggests
switching to an older SDK major if a framework/Python version is not
supported on the current one. Currently it mentions specific SDK
versions. Make it more generic so that it doesn't get out of date if we
release a new major.

-The versions above apply for Sentry Python SDK version `2.0+`, which drops support for some legacy Python and framework versions. If you're looking to use Sentry with older Python or framework versions, consider using an SDK version from the `1.x` major line of releases.
