sparse decoration warning is unclear

[levBagryansky]

Now sparse decoration warning looks like```

[INFO] Shift #0 via 'globals-to-abstracts' made no changes
[INFO] Shift #0 via 'globals-to-abstracts' made no changes
[INFO] Shift #0 via 'globals-to-abstracts' made no changes
Error:  net.sf.saxon.style.XSLText@62f2a4fe: Warnings identified: Sparse decoration is prohibited; 
Error:  #fatalError(): Processing terminated by xsl:message at line 32 in fail-on-warnings.xsl; SystemID: file:///org/eolang/parser/fail-on-warnings.xsl; Line#: 32; Column#: 17
[INFO] Shift #0 via 'globals-to-abstracts' made no changes
[INFO] Shift #0 via 'globals-to-abstracts' made no changes

So it does not provide information in which .eo file the mistake happened. Let's expand it

@maxonfjvipon WDYT?

@levBagryansky it's not about only sparse-decoration warning. It's about all warnings at all. Replace sparse-decoration with any other warning and you get the same story.
And you're right, it would be nice to extend the log info
Want to take it on?

[levBagryansky]

@maxonfjvipon yes, let me try

[maxonfjvipon]

@levBagryansky sure, go ahead
