Resolve the plugin and SDKs from Gitea

PluginDownloadURL moves off github:// to a templated Gitea release URL.
Pulumi interpolates ${VERSION}, then appends
pulumi-resource-dokploy-v<version>-<os>-<arch>.tar.gz -- which is what
the GoReleaser archive template already produces. Schema, bridge
metadata and all four SDKs regenerated to carry it.

Releases publish to this instance's npm, PyPI, NuGet and Go registries
using the GITEA_TOKEN that Gitea injects, so no secrets need
configuring.

The Go SDK keeps its github.com module path, which is exactly why it
goes to Gitea's Go registry: pointing GOPROXY there is what makes that
path resolve at all. Verified locally by serving the module zip from a
file proxy and building a consumer against it -- note zip -D, without
which go get rejects the archive's directory entries.
