Strip Liberty Config LS jar version when copying over into build/server directory

[kathrynkodama]

In the build.gradle, we strip the versions of the LS jars so that we don't have to update the launcher code for new versions.

liberty-tools-intellij/build.gradle

Line 72 in 345cb9c

rename '^(.*)(-[0-9]+.[0-9]+.[0-9]+(-SNAPSHOT)?)(.*)$', '$1$4'

The version is still present for the Liberty Config LS jars:

liberty-tools-intellij/src/main/java/io/openliberty/tools/intellij/liberty/lsp/LibertyConfigLanguageServer.java

Line 35 in 9dd8655

File libertyServerPath = new File(descriptor.getPluginPath().toFile(), "lib/server/liberty-langserver-1.0-SNAPSHOT-jar-with-dependencies.jar");
