feat: add {version} placeholder interpolation for URL-type sources#3
Conversation
The url field now supports a {version} placeholder that gets resolved
to the source's version field value before fetching. This makes version
the single source of truth, preventing drift between the URL path and
the version field (e.g. kubevirt url pointing at v1.7.1 while version
says v1.6.1). Renovate only needs to bump version, and the URL stays
correct automatically.
Validation requires {version} to be present in all url-type source URLs
and rejects it when version is empty.

Summary
{version}placeholder in theurlfield, resolved to theversionvalue before fetchingtype: urlsources include the{version}placeholder, preventing silent version drift between URL path and version fieldsource.schema.jsonto document the interpolation behaviorMotivation
The
versionfield and URL path could drift independently, as happened with kubevirt (url pointed at v1.7.1, version said v1.6.1) and gateway-api (url at v1.5.0, version at v1.2.1). With interpolation,versionbecomes the single source of truth. Renovate's custom manager only needs to bumpversion, and the URL stays correct automatically.Test plan
