Make new text file tooltip messages update

#27864

Motivation and Context

As the reason that the new text file name is invalid changes, the displayed text does not change.
The user needs to see an up-to-date error reason.

How Has This Been Tested?

1. Create a folder with a file in it - e.g. file.txt
2. Click "+", New text file, first blank out the whole file name and file type. "File name cannot be empty" is displayed in the tooltip -good.
3. Now type a name that exactly matches the name of the other file in the folder - file.txt. The tooltip displays again, but it still says "File name cannot be empty".

After this fix, at step (3) the tooltip pops up and says "file.txt already exists"
and as you blank out the filename, put a single "." etc, the tooltip text changes.

These are the other places that this type of tooltip code happens where the tooltip text gets updated on-the-fly. The same fix as in #27958 applies.

Note: I cannot see how to really test this one. To get to this try-catch the user has to be able to get past the char-by-char validation which actually will have caught the same validation checks. Looking through the code in try{} there are not any obvious other errors that will be thrown. In any case, this extra code will be needed here, just as in newfilemenu.js and #27958

@DeepDiver1975 this is another little easy fix, if you are in the mood for reviewing.

if needed for the tests, please backport to stable10

Backport in #28055
This is exactly the same bug for the case when creating a new (text) file, compared to the other bug when renaming a file. It is much cleaner that both fixes appear consistently in the same point release series.
