A more informative "wrong version" message from version manager

[codificat]

Problem statement

I requested a new patch version for the adviser repo and Kebechet said:

Wrong version specifier found in sources: 21.3

(link to the update: https://github.com/thoth-station/adviser/issues/2360#issuecomment-1177599348)

and then closed my issue.

The problem is that I don't know where this "wrong version" comes from (adviser is currently at version 0.56.0), why/how is it "wrong", how/where can I make it "not wrong"...

High-level Goals

Improve the messaging provided by Kebechet in this situation to help the user better understand what happened and how to proceed next.

Proposal description

The message from Kebechet could be expanded to include things like:

• a pointer to the source (file path?) where the wrong version was found
• what does "wrong" mean
• what would be "not wrong"
• a short message with next steps ("I am now going to close this issue, you should do X, Y, Z next...")
• possibly: kebechet version information to help identify the bot, in case a bug must be reported

Acceptance Criteria

• [ ] A more elaborate message is provided by Kebechet when a VersionError appears
