Bump public chains submodule to v1.4.6

[AlexVarin2001]

Bumps foundation/src/main/resources/public from c2280a51 (Injective method spec, #263) to 5ff10f2 (v1.4.6).

Registry commits this pulls in:

• Add peaq (eth_getProof support #267) — needed so the peaq upstreams added to dshackle-public-multiregion (drpcorg/infra#5414) resolve instead of being skipped with Chain is unknown: peaq
• golden lower bound for arc (Validate old blocks #268)
• Fix algorand spec (make link to specific commit for rpc.returndata.limit param #269)
• Celestia cosmos (Fix validation #270), Celestia block time (Fix missing spans #271), Celestia ws methods (Maximum value quorum for BroadcastReader #272)
• unban caplin hoodi (log quorum errors at debug level #266)

After merge, public-multiregion needs a rebuild/redeploy (Dshackle Provider: public-multiregion workflow, ref master) to pick this up.
