`ApacheNoticeResourceTransformer` not injecting project name

[JackPGreen]

Affected version

3.6.0

Bug description

When generating a NOTICE using ApacheNoticeResourceTransformer, the project name is not injected (or more likely, resolved) as expected, e.g. the output is:

// ------------------------------------------------------------------
// NOTICE file corresponding to the section 4d of The Apache License,
// Version 2.0, in this case for
// ------------------------------------------------------------------

Not, something like this as you might expect:
https://github.com/apache/amoro/blob/0e34e89dcfc8b5c5b5da285786004965d5b70bc6/NOTICE-binary#L1-L4

maven-shade-plugin/src/main/java/org/apache/maven/plugins/shade/resource/ApacheNoticeResourceTransformer.java

Line 100 in 256eab8

entries.add(preamble1 + projectName + preamble2);

From looking at the code, projectName is never set:

maven-shade-plugin/src/main/java/org/apache/maven/plugins/shade/resource/ApacheNoticeResourceTransformer.java

Line 48 in 256eab8

String projectName = ""; // MSHADE-101 :: NullPointerException when projectName is missing

It can be injected via Maven in a mojo as used elsewhere, but I don't think that's accessible here.

maven-shade-plugin/src/main/java/org/apache/maven/plugins/shade/mojo/ShadeMojo.java

Lines 105 to 109 in 256eab8

	/**
	* The current Maven project.
	*/
	@Parameter(defaultValue = "${project}", readonly = true, required = true)
	private MavenProject project;

Note - the fix in 88f188d only makes sense if it used to work, but I can't get it to work with my sample project even going back to shade plugin 1.6.
