Investigate Linux build failures

[anusreelakshmi934]

In many of the tests in Linux GHA we are encountering various errors like the below ones:

A Build that ran had these failures - https://github.com/OpenLiberty/liberty-tools-intellij/actions/runs/10846737003/job/30100325255

• Start in Container tests failing in GradleSingleModMPSIDProjectTest and MavenSingleModMPSIDProjectTest #983

• Unable to insert entry in config file : server.env in LINUX & Windows #988

• Resolve Linux build failures introduced by PR 553 #564

• Timed out waiting for message CWWKE0036I in log:/home/runner/work/liberty-tools-intellij/liberty-tools-intellij/liberty-tools intellij/src/test/resources/projects/gradle/singleModGradleMP/build/wlp/usr/servers/defaultServer/logs/messages.log
  From one of the failure videos we can see that the dev mode is not getting started even after waiting for 90 seconds. And it is trying to stop the dev mode after that which fails since the dev mode did not fully started.
