[Feature request] Detect «warning: mnemonic $N$ not found in menu caption Back There»

[Kristinita]

1. Request

It would be nice, if package_reviewer will detect, if developer make Main.sublime-menu file wrong and users see in console, for example:

warning: mnemonic b not found in menu caption Back There

2. Justification

I fixed this error in 4 Sublime Text packages:

• SortBy,
• Back There,
• esLintAutoFix,
• unicode-character-insert.

On this basis, I am assuming that the error may be in other packages.

3. Desirable behavior

package_reviewer detect “mnemonic not found” error → information about error include in package_reviewer report.

Thanks.
