Is there any reason we should worry about a $schema field matching these shorter version strings but being something other than a longer URL (like the ones that used to be here)?

[EricDahlvang]

While the entire path is more correct, this seems less restrictive. I had a mistake in a manifest schema path, while the rest of the manifest was correct. I do not feel strongly about this though. If you object, we can skip this change.

Maybe we should be checking the $version, instead of the #schema path. Considering, our previous .schema had no version in the $id path: https://schemas.botframework.com/schemas/skills/v2.0/skill-manifest.json

"$id": "https://schemas.botframework.com/schemas/skills/skill-manifest.json",

@beyackle adjusted to endsWith '{v}/skill-manifest.json' and remove v2.0, considering the above comment
