Strengthen the dependencies warning

[adhilto]

💡 Summary

Strengthen the warning presented when the proper versions of ScubaGear's dependencies are not installed. Perhaps add something like "ScubaGear may not function properly until the supporting modules are installed."

Motivation and context

The current warning is very ignorable -- and sometimes you can get away with ignoring it. But ignoring it can also cause significant exceptions to occur. Strengthening the warning would help the users understand the potential risks of ignoring it.

Implementation notes

The warning currently reads as:

The required supporting PowerShell modules are not installed with a supported version.
Run Initialize-SCuBA to install all required dependencies.
See Get-Help Initialize-SCuBA for more help.

See PowerShell/ScubaGear/Dependencies.ps1.

Acceptance criteria

The warning clearly states the risks involved.
