fix: flaky e2e-p2p test

[benesjan]

Fixes #3654

Note: Lasse had a good hunch that it's most likely caused by different nodes using the same l1 publisher private key. This PR changes this and uses different accounts for different nodes. I am quite confident that that is the culprit so I will close the issue.

No metrics with a significant change found.

Detailed results

All benchmarks are run on txs on the Benchmarking contract on the repository. Each tx consists of a batch call to create_note and increment_balance, which guarantees that each tx has a private call, a nested private call, a public call, and a nested public call, as well as an emitted private note, an unencrypted log, and public storage read and write.

This benchmark source data is available in JSON format on S3 here.

Values are compared against data from master at commit c4153936 and shown if the difference exceeds 1%.
