Version Catalog code snippets

[trevjonez]

Add version catalog examples to the plugin portal gui.

Expected Behavior

transform the ID as the default name?
for example jetbrain tf plugin might look like this:

[plugins]
org-jetbrains-gradle-terraform = { id = "org.jetbrains.gradle.terraform", version = "1.4.2" }

and maybe link to the gradle version catalog toml documentation

Context

Make pulling in another plugin faster while also encouraging people to use version catalogs.
