[FR] Update the MITRE ATT&CK® Navigator version

### Repository Feature

None

### Problem Description

When opening of the many MITRE ATT&CK® Navigator links within this repository a warning message pop-ups that says "Uploaded layer version (4.4) is out of date. Please update to v4.5 for optimal compatibility."

It shows up on page load then goes away after a few seconds. Additionally, not all the links go to the most recent version either (using different Gist versions).

It would be nice if the Navigator would accurately display the most current detection rule coverage.

### Desired Solution

- The `versions.layer` is upgraded along with the associated JSON if necessary to address the warning message (and before the old version no longer works).
- Update the short url destination of
- It appears that it may be an older version when compared to other layers from Gist
- Consider making the links consistent between the different locations
- (front page, README.md)
- "ATT&CK Navigator" chip links to
- The short url redirects to
-
- "ATT&CK Navigator" chip links to (again)
- "Coverage by platform: navigator" links to [this appears to be newer than the other location and/or displays additional coverage]

### Considered Alternatives

_No response_

### Additional Context

This is likely related to #2389 as it also requests updates to the navigator output.
