Don't report "Non-parseable POM" error

[angelozerr]

When your XML has some syntax validation:

There is the error

Description	Resource	Path	Location	Type
Non-parseable POM C:\Users\azerr\eclipse-workspace-2023\test-xml\pom2.xml: unexpected character in markup   (position: START_TAG seen ...xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">\r\n    \r\n  < ... @5:5) 	pom2.xml	/test-xml	line 5	Language Servers

As it is a syntax error, it should not be reported, the syntax validation is managed correctly with LemMinx.

This would be very low priority; as it can still be useful to report errors like Maven would report them so people can refer to Maven error messages when trying to troubleshot things.

For me it is a technical error that XML syntax is invalid and more the range is very strange. You have 2 errors in this case about syntax validation that LemMinx takes care, so IMHO it should be skipped.
