Bump dev.zacsweers.metro:gradle-plugin from 0.9.3 to 0.9.4

[dependabot]

Bumps dev.zacsweers.metro:gradle-plugin from 0.9.3 to 0.9.4.

Release notes

Sourced from dev.zacsweers.metro:gradle-plugin's releases.

0.9.4

Enhancements

• [IR] Support generation of scalar multibinding sets that use @ElementsIntoSet source bindings. Previously these would always use a SetFactory under the hood.
• [IR] Refactor multibinding getter logic to align with all other binding field/getter logic, allowing more precise generation of multibindings based on different contextual needs (scalar, Provider, etc representations).

Fixes

• [IR] Fix accidental potential for runtime eager calls to non-initialized bindings in some multi-level multibinding scenarios.
• [IR] Always use a provider field if multiple provider and scalar refs are found. Previously we would possibly use just a scalar getter field wrapped in InstanceFactory for provider refs.
• [IR / Dagger Interop] Ensure @BindsOptionalOf bindings that are satisfied by scoped bindings use the scoped instance.
• [IR / Reports] Don't de-dupe alias/memberinject bindings in graph metadata reports if one is already present.

Changes

• Remove -checkdiscard rules from embedded proguard rules.
