Fix hyperlink for elements of the type 'KtFile'

[biazmoreira]

Issue: #2340

Description:

IntelliJ (and consequently Android Studio), considers the following implementation when enabling hyperlink in its terminal emulator: AbstractFileHyperlinkFilter

I noticed that there were two issues happening related to hyperlinks not being enabled in the output of detect:

1. Files outside the considered project scope by IntelliJ (/build, etc) were not hyperlinking because IntelliJ uses the Filter above, and consequently, the file must be inside the considered project scope by IntelliJ in order to be Highlighted.
2. And output with two file paths in the same line -- this usually happens for elements of type KtFile, classes and functions seem to hyperlink just fine. I didn’t find a reason as to why this happens, but I think it’s out of the scope of Detekt to fix it -- other tools have the same problem.

Example of the point 2 before the changes I applied in this PR:

Fix:
A fix for point 2 is to simplify the Entity name in the case of Files by getting the file name without the absolute path since the path is also written along with the output.

Regarding other terminal emulators, it really depends on the terminal emulator you're using to specify the way of hyperlinking: https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda.
This only tackles the IntelliJ Terminal Emulator.
