[CI] Seed specific failure of RemoveCorruptedShardDataCommandTests.testCorruptedTranslog

[droberts195]

RemoveCorruptedShardDataCommandTests.testCorruptedTranslog fails reproducibly on the 7.x branch (confirmed using commit bb91291) with this repro command:

./gradlew ':server:test' --tests "org.elasticsearch.index.shard.RemoveCorruptedShardDataCommandTests.testCorruptedTranslog" \
  -Dtests.seed=73D8350A7F9C1987 \
  -Dtests.security.manager=true \
  -Dtests.locale=sl \
  -Dtests.timezone=Europe/Brussels \
  -Dcompiler.java=12 \
  -Druntime.java=12

and this error:

  2> java.lang.AssertionError: minTranslogGen [11] is higher than generation [10]
        at __randomizedtesting.SeedInfo.seed([73D8350A7F9C1987:41A0283FE58FDB57]:0)

        at org.elasticsearch.index.shard.RemoveCorruptedShardDataCommandTests.testCorruptedTranslog(RemoveCorruptedShardDataCommandTests.java:220)

If you change the seed then it doesn't fail.
