fix(ci): flaky Fabric 2.x run tx endpoint test

[petermetz]

Describe the bug

The test below fails occasionally and only on the CI servers of GHA, not reproducible on development machines unfortunately.
packages/cactus-plugin-ledger-connector-fabric/src/test/typescript/integration/fabric-v2-2-x/run-transaction-endpoint-v1.test.ts

To Reproduce

Keep submitting PRs and you'll hit this issue every once in a while, forcing you to re-run the CI and then have it pass...

Expected behavior

Tests are as stable as possible.

Additional context

This seems to be the last bug standing after several other ones were fixed recently as part of the effort to make #656 possible.
Guess on what might be going wrong: The Fabric 2.x AIO container may be hanging at boot with a race condition that it cannot recover from. This is more likely than it being just a not enough time on slow hardware type of thing because usually 3 out of 4 runs in the CI matrix pass in 30 minutes but then the 4th one takes an hour+ and still times out...
