YAML blocks will not preserve their single quotes when using format tool

[margaretkennedy]

The salmon-formatter's pretty_yaml plugin changes single quotes to double quotes in YAML code blocks.

• Neither nor comments prevent this
• The Docker image at ghcr.io/deephaven/salmon-formatter:1 has its own bundled /dprint.json that ignores the local config file
• Suggested fix: Configure the YAML plugin to preserve quotes or respect dprint-ignore comments in markdown code blocks
