Clarify that bundle info takes a gem name

[manuraj17]

What was the end-user or developer problem that led to this PR?

Relates to #6212

bundle info [GEM] command's description didn't mention that only gem name is supported and adding the version was not required. The issue reported was around that confusion. One the suggestion in the discussion was to update the documentation which seemed like a fast thing to do for now.

What is your fix for the problem, implemented in this PR?

Update the man info.

Make sure the following tasks are checked

• Describe the problem / feature
• Write tests for features and bug fixes
• Write code to solve the problem
• Make sure you follow the current code style and write meaningful commit messages without tags
