Constrain Renovate updates for Refined Storage and TerraBlender by Minecraft line

[Copilot]

Renovate was proposing cross-line upgrades for refinedstorage-neoforge and TerraBlender-neoforge, applying latest versions regardless of modpack Minecraft target. This PR scopes those updates so 1.21.1 packs stay on the 1.21-compatible line and 26.1 packs stay on the 26.1-compatible line.

• What changed

  • Added file-scoped Maven packageRules in renovate.json for:
    • com.refinedmods.refinedstorage:refinedstorage-neoforge
    • com.github.glitchfiend:TerraBlender-neoforge
  • Rules are matched by modpack path (modpacks/**/1.21.1/**/pom.xml vs modpacks/**/26.1*/**/pom.xml) and constrained with allowedVersions.

• Version-line constraints introduced

  • Refined Storage
    • 1.21.1 modpacks: ^2.x
    • 26.1 modpacks: ^3.x
  • TerraBlender
    • 1.21.1 modpacks: ^1.21-...
    • 26.1 modpacks: ^26.1...
