fix(docs): remove stale @ts-expect-error directives in docs examples

[benesjan]

Docs build was broken and it resulted in flakes in 2 of my other PRs:

• fix(stdlib): decode EthAddress, FunctionSelector and wrapped field structs in AbiDecoder #21926
• fix(pxe): robust error handling in message processing #21093

I am not exactly sure why this happened but the changes here seem harmless so I think we can just merge this to not cause pain to other people today.

AI Summary

• Removed 9 unused @ts-expect-error directives from docs/examples/ts/example_swap/index.ts
• Removed 6 unused @ts-expect-error directives from docs/examples/ts/token_bridge/index.ts

These directives were suppressing viem type inference errors for JSON-imported ABIs, but @aztec/viem@2.38.2 now handles this correctly. The stale directives cause TS2578: Unused '@ts-expect-error' directive errors during the docs examples validation pipeline (docs/bootstrap.sh).

Test plan

• Verified example_swap passes tsc --noEmit locally
• Verified token_bridge passes tsc --noEmit locally

All directives had the same comment: // @ts-expect-error - viem type inference doesn't work with JSON-imported ABIs. The underlying viem issue has been resolved in @aztec/viem@2.38.2.

Closing as I was retarded and didn't manage to read #enginnering channel where it was written that there is already a fix on next. Sadge
