ci: switch PR title check to step-security/action-semantic-pull-request

[nathanklick]

Summary

• Replaces step-security/conventional-pr-title-action@v3.2.2 with step-security/action-semantic-pull-request@v6.1.2 in .github/workflows/flow-pull-request-formatting.yaml.
• Action pinned by commit SHA (75d2dd5deafa3e9fccc1626ecd58d076ed1d2c79) per repo convention.
• Uses the action's default configuration, which enforces the standard Conventional Commits types.

Test plan

• Verify the PR Formatting / Title Check job runs against this PR and passes on this conventionally-formatted title.
• Open a follow-up draft PR with a non-conventional title to confirm the check fails as expected.
