Align build.yaml shell settings with SarifMark

[Copilot]

Pull Request

Description

The build-docs job runs on windows-latest where PowerShell is the default shell, but several steps use bash-specific syntax like $(date +'%Y-%m-%d') and commands like cat/echo. Added explicit shell: bash to these steps to match SarifMark's approach.

Steps updated:

• 4 Pandoc HTML generation steps using $(date +'%Y-%m-%d') for date metadata
• 2 Display steps using cat and echo for quality report output

Type of Change

• Bug fix (non-breaking change which fixes an issue)
