[utils] coverity: ignore uncaught 'fmt::FormatError' exception

[Rechi]

Description

Disable an fmt::FormatError uncaught exception issue at coverity.

Motivation and Context

The windows coverity project currently shows 63 warnings because of the exception thrown in fmt.
If fmt throws an exception it should result in a crash as in that case the format string is wrong.

How Has This Been Tested?

Next coverity after this has been merged will tell if it does what I expect.

Instead of hard-crashing, what about this as a workaround? #11915

When the fmt conversion happened, one of the strings had a wrong format type and it took a long time to track it down. Adding this log message instead of crashing would be helpful in that case.

A wrong format is not a runtime error. Having the app crash is much better than hiding the error.

But crash without error logging? And now a translator can maliciously or accidentally crash Kodi when a new language is installed.

This is also a point where I must say that a "try" is helpful, after removing from the addons it makes me almost impossible to find the source caused.

Why not the "try" log the error and "throw" again?
