Rename file name to adequately describes the content (Recent Edits)

[sun-flat-yamada]

Summary

• Rename file name to adequately describes the content.
• The following workshop contents are not "Recently changed files" but "Recent edits", so I renamed the files appropriately.

01-Navigation\3-Navigate_to_somewhere_youve_already_been\3.3-Recently_changed_files.cs
  -> 3.3-Recent_edits.cs

This topic is touched upon in the following discussion:

#28 (comment)

Issue

#30
Incorrect file name for "Recent Edits" workshop

#20
Proposal for creating a Japanese localized version

How did I test it?

• I have only conducted self-verification using a translation tool.
• If you have a reliable Japanese person, I would like to ask for a third-party review.

Good days!

@sun-flat-yamada Would you mind making the change in the English version, too? That way we keep things consistent from the start.

@ sun-flat-yamada英語版も変更していただけませんか。そうすれば、最初から一貫性を保つことができます。

Hi, @maartenba .

OK, of course. I'll set up an Issue and tie this PR to it.
I should have started an Issue first. I'm sorry about that.

Here is an issue :
#30

I will update this PR (and I'll update English version soon).
