Update IntelliJ compatibility bounds correctly

[CRogers]

Before this PR

In #874, I tried to update the minimum intellij version this is listed to work with. However, it didn't work as the patchPluginXml task changes the plugin.xml file.

After this PR

Use the correct intellij version bound.

==COMMIT_MSG== Update intellij compatibility range in IntelliJ plugin plugin.xml metadata file, but hopefully correctly this time. ==COMMIT_MSG==

Possible downsides?

I ran ./gradlew buildPlugin then checked that the plugin jar contains this in it's plugin.xml:

<idea-version since-build="193" />

by running vim idea-plugin/build/libs/idea-plugin-2.31.0-1-gfdceb49.jar
