RSPEC tag links for context when browsing recipes

[timtebeek]

A lot of our static analysis recipes link to an external specification. We can provide additional context by converting those into a link.

For example:

• https://docs.openrewrite.org/recipes/java/logging/parameterizedlogging
• https://sonarsource.github.io/rspec/#/rspec/S2629
• https://sonarsource.github.io/rspec/#/rspec/S3457

Indeed now works: https://openrewrite.github.io/rewrite-recipe-markdown-generator/reference/recipes/java/logging/parameterizedlogging.html
