chore: skip fee estimate example

[Dosik13]

Description:

Skip the fee_estimate_query example in the run-examples Task so a fresh
local mirror node doesn't fail the run.

• Add fee_estimate_query to the skip list in Taskfile.yml with a comment
  explaining the mirror-node-sync flake

Notes for reviewer:

The example itself works against a steady-state network — the failure mode is
specifically that a freshly-started local mirror node hasn't ingested the
operator's state when run-examples invokes it back-to-back with all the
others.
