Serge Tupchii 99e892b5c4 chore: bump ekka to 0.15.0 
ekka 0.15.0 uses mria 0.5.0, which adds several fixes, enhancements and features:
  - protect `mria:join/1,2` with a global lock
  - implement new function `mria:sync_transaction/4,3,2`, which waits for
    a transaction replication to be ready on the local node
    (if the local node is a replicant)
  - optimize `mria:running_nodes/0`
  - optimize `mria:ro_transaction/2` when called on a replicant node.

Fixes: EMQX-9588 (#10380), EMQX-9102, EMQX-9152, EMQX-9213

Add several fixes, enhancements and features in Mria:

  • protect mria:join/1,2 with a global lock to prevent conflicts between two nodes trying to join each other simultaneously Mria PR
  • implement new function mria:sync_transaction/4,3,2, which blocks the caller until a transaction is imported to the local node (if the local node is a replicant, otherwise, it behaves exactly the same as mria:transaction/3,2) Mria PR
  • optimize mria:running_nodes/0 Mria PR
  • optimize mria:ro_transaction/2 when called on a replicant node Mria PR.
