Filter out org.utbot.*Exceptions from Summaries

[alisevych]

Description

All org.utbot.*Exceptions should not be shown in Java docs (tag @utbot.throwsException is for user code exceptions only).

Expected behavior

@utbot.throwsException should be used only for exceptions from user code.
Need to filter out all of exceptions with classname org.utbot.* from Java docs generation.

Context

The following bugs seeped without this restriction:

• Support artificial errors rendering in summaries #1739
• Timeout exception (internal of UtBot) is dispayed in Summaries #1832
