Use bash shell for Lint step to ensure early failure

[adamtheturtle]

PowerShell does not fail on intermediate command failures by default. By using bash shell, we ensure that any failing command causes the step to fail immediately.

See adamtheturtle/doccmd#720 for the original learning.

Note

CI workflow updates

• Sets shell: bash for the Lint step to ensure the job fails if any command fails (PowerShell may not)
• Adds SKIP env to bypass hadolint on Windows runners where it isn't available

No application code changes; only .github/workflows/lint.yml adjusted.
