Bring fork back in sync with upstream while preserving Dell recovery support

[Copilot]

The fork had drifted behind the upstream project and needed a clean sync without losing the Dell-specific recovery-image behavior introduced by the fork. This merge brings the branch back in line with upstream/main while preserving the forced-download and forced-flash logic required for Dell NVMe BIOS recovery recreation after reimaging.

• Summary

  • Synced the fork with the current upstream main branch.
  • Resolved merge conflicts across the BIOS package and BIOS update scripts.
  • Kept the fork’s Dell recovery workflow intact without reverting upstream fixes.

• Changes

  • Updated README.md to reflect the upstream project while documenting the fork’s Dell recovery-image workflow.
  • Merged the current upstream version of Invoke-CMDownloadBIOSPackage.ps1 and retained the opt-in force-download behavior needed for Dell NVMe recovery-image recreation.
  • Preserved compatibility with both the legacy SMSTSForceDellBIOSFlash task sequence variable and the newer SMSTSForceBIOSDownload alias.
  • Kept the Dell-specific /f logic in Invoke-DellBIOSUpdate.ps1 enabled when explicitly requested, while staying aligned with the upstream script behavior.

• Example

# Task sequence pattern for Dell NVMe recovery image recreation
Set Task Sequence Variable
  Name:  SMSTSForceDellBIOSFlash
  Value: True

Invoke-CMDownloadBIOSPackage.ps1 ...
Invoke-DellBIOSUpdate.ps1 -Force

🟡 Changes recommended

The README currently overstates SMSTSForceBIOSDownload behavior and the newly added legacy script disables TLS certificate validation unconditionally.

Pull request overview

This PR syncs the fork with current upstream changes while keeping (and documenting) the Dell NVMe recovery-image recreation workflow, including opt-in “force download” behavior so a same-version BIOS re-application can be staged for a subsequent forced flash.

Changes:

• Updated README.md to reflect upstream and describe the fork’s Dell recovery-image workflow and TS variables.
• Updated Invoke-CMDownloadBIOSPackage.ps1 to v3.0.6, including refined force-download handling and a fix for model matching in live task sequences.
• Added Invoke-CMDownloadBIOSPackage_Legacy.ps1 as a legacy copy of the older implementation.
