📖 [Docs]: Document the Pester major-version lock in the test pipeline

[Marius Storhaug (MariusStorhaug)]

The pipeline README now documents that module test files lock Pester to the 6.x major and the Invoke-Pester step installs a matching version, so contributors understand how the test framework is constrained.

Changed: README documents the Pester major-version lock

The "Test module" section now states the #Requires form test files use and notes that minor and patch updates flow in automatically while a new major stays a deliberate, reviewed change.

Technical Details

• Updates the "Test module" section of README.md.
• Part of the dependency-management epic Dependency management for PowerShell scripts and modules #356.

Pull request overview

This PR updates the project README to document a dependency-management convention in the test pipeline: keeping Pester locked to the 6.x major series so minor/patch updates flow automatically while major upgrades remain deliberate.

Changes:

• Document that module test files should lock Pester to the 6.x major version via #Requires -Modules ... in the “Test module” pipeline section.
• Explain the intended behavior/benefit in conjunction with the PSModule/Invoke-Pester GitHub Action.
