[DOCS] Onedir Security Support

Description
In the previous case #62681 and others like it the new statement from SALT is to install the Onedir version of salt. This is a version of salt that will have a self-contained version of python and all the salt components. Yet from a security aspect, it does not explain how it handles the added components (salt-provided version of python) when a security issue occurs.

With the original salt rpm the majority of the required packages were provided from EPEL or Core REPO's. So updates to dependencies like python were being handled by OS.

Now per https://docs.saltproject.io/salt/install-guide/en/latest/topics/upgrade.html#onedir salt is basically advising all users to move to a onedir installation

Onedir is Salt’s new packaging system (as of 3005). Onedir stands for “one directory” because the goal is to provide a single directory containing all the executables that Salt needs. It includes the version of Python needed by Salt and its required dependencies. The onedir packages simplify the installation process because they allow you to use Salt out of the box without installing Python or other dependencies first. See What is onedir? for more information.

Beginning with the release of Salt 3005 (Phosphorus), the Salt Project will begin replacing the old packaging system with the Tiamat packaging system. The Salt Project strongly recommends upgrading to onedir to continue receiving Salt version updates. See Upgrade to onedir for more information.

What is Salts model for handling security vulns found in the dependency packages that salt is bundling?

Suggested Fix
Include documentation around onedir on how dependency updating will occur. For example, if a vuln is in a dependency (example bundled python) we will strike to have an update for salt 1 month after the upstream fix has been provided. Or be clear if you don't offer any assurances as at. This should be known as this a big departure in salt and users be aware.

Type of documentation
This could be Salt documentation, Salt modules, the Salt Repo or the Getting Started guide.
