Pull request overview

This PR updates the Azure Container Linux (ACL) marketplace base image version used by the VHD builder pipelines, aligning the build inputs to 3.20260616.01.

Changes:

• Bump IMG_VERSION for ACL Gen2 builds (x64 + arm64, FIPS + non-FIPS, Trusted Launch) from 3.20260602.01 to 3.20260616.01 in the main VHD builder pipeline.
• Apply the same ACL image version bump in the VHD builder release pipeline to keep both pipelines consistent.

RCA: Likely PR-caused ACL marketplace image mapping failure: ACL TL/FIPS/ARM64 lanes fail Build VHD after expected SIG image version is not found; downstream BCC/disk artifacts are side effects. Secondary Ubuntu 22.04 CIS 6.1.3.1 recurrence is tracked under #38501652.

Confidence: High for the primary signature. Corroborated by timeline/status, focused failed logs, associated changes, and the flakiness wiki before publishing.

Strongest alternative: transient SIG replication/build infra; less likely because failures align with ACL lanes and this PR directly bumps ACL marketplace image.

Recommended owner/action: PR #8748 author / ACL marketplace image owner: verify 3.20260616.01 maps to published SIG versions for all ACL variants.
