sdk: repin to fizzy SDK 0.2.30

[github-actions]

Repins the plugin from fizzy SDK 0.2.29 to 0.2.30, because the build fails against it.

• build.zig.zon: the sdk-v0.2.30 release asset and its hash
• plugin.zig.zon: .version → 0.1.4, .min_sdk_version → 0.2.30

It does not build against the new SDK yet, so this is a draft: the plugin needs changes on this branch first. The end of the build:

Opened by fizzyedit/plugin-build-action's repin workflow.

Superseded by #13, which moves the template to Zig 0.17 and carries this repin to SDK 0.2.30.
