Print info about finally selected toolchain

[HannesWell]

New feature, improvement proposal

The select-jdk-toolchain goal is very handy but one thing I'm missing is an info print-out about the finally selected toolchain.
Currently the print-out is for example only

[INFO] --- toolchains:3.2.0:select-jdk-toolchain (default) @ my.project ---
[INFO] Found 4 possible jdks: [C:\java\temurin-jdk-25, C:\java\temurin-jdk8, C:\java\graalvm-ce-java17, C:\java\temurin-jdk-21]

Listing all JDK's found is good, but I find it confusing that the finally selected one is not specified and then I'm concerned the wrong one might be selected.
The old toolchain goal is a bit more specific in this regard:

 [INFO] --- toolchains:3.2.0:toolchain (default) @ my.project ---
[INFO] Required toolchain: jdk [ version='17' ]
[INFO] Found matching toolchain for type jdk: JDK[/java/temurin/jdk-17/latest]

There is already a corresponding debug print-out, and with debug print-out the information is satisfying:

maven-toolchains-plugin/src/main/java/org/apache/maven/plugins/toolchain/jdk/SelectJdkToolchainMojo.java

Line 232 in 1f2ca23

getLog().debug("Found matching JDK toolchain: " + toolchain);

My suggestion is to turn that into a info message and maybe adjust the wording to Selected matching JDK toolchain.
If you agree I can create a PR to adjust it.

In fact, if a toolchain is read from the toolchains.xml then there is already a suitable info log

maven-toolchains-plugin/src/main/java/org/apache/maven/plugins/toolchain/jdk/SelectJdkToolchainMojo.java

Line 198 in 1f2ca23

getLog().info("Found matching JDK toolchain: " + toolchain);

So instead maybe just the debug massage about the matching discovered JDK should be turned into an info?

maven-toolchains-plugin/src/main/java/org/apache/maven/plugins/toolchain/jdk/SelectJdkToolchainMojo.java

Line 210 in 1f2ca23

getLog().debug("Discovered matching JDK toolchain: " + toolchain);
