Terminology, language

Anumber of mistakes in the foll. KI:

--------------
4.2.3. Theia is going in CrashLoopBackOff state when creating a workspace on IBM Power Systems.

To work around this issue, you can either refresh the browser or add more memory to the devfile, so that the Theia plugin has more space to run.
--------------

• Theia -> Che-Theia
• No period at the end of headings
• plugin -> plug-in

Plus I would suggest including instructions on how to perform the workaround ("add more memory to the devfile").
