build(deps): bump the actions-updates group across 1 directory with 2 updates

[dependabot]

Bumps the actions-updates group with 2 updates in the / directory: step-security/harden-runner and docker/setup-buildx-action.

Updates step-security/harden-runner from 2.20.1 to 2.21.1

Release notes

Sourced from step-security/harden-runner's releases.

v2.21.1

What's Changed

• Improved performance of the disable-sudo feature.
• Fixed an issue in the Community tier where new endpoints required by the GitHub Actions runner were not being implicitly allowed in block mode.
• Fixed the Harden-Runner post step failing on Linux distributions that do not have a merged /usr filesystem layout (for example Debian 11), where /usr/bin/echo does not exist. This mainly affected self-hosted runners.
• Documentation updates: clarified which features are in the Community (free) vs Enterprise tier.

Full Changelog: step-security/harden-runner@v2.21.0...v2.21.1

v2.21.0

What's Changed

• Support for denied endpoints in block mode. This is included in the enterprise tier. Customers can deny outbound calls, for example, to public package registries.
• Improved Support for AWS CodeBuild GitHub Actions Runners.
• Bug fixes.

[dependabot]

Looks like these dependencies are updatable in another way, so this is no longer needed.
