Fix Maven Wrapper EOL issues

[mches]

I hit a snag trying Testcontainers Cloud Desktop for the first time with Java on Windows due to the line endings of the Maven Wrapper script on a fresh clone. On Windows, core.autocrlf defaults to true, but mvnw needs to have LF line endings and mvnw.cmd needs to have CRLF line endings, regardless of platform. Up until Maven Wrapper 3.3.1, it was also the case that .mvn/wrapper/maven-wrapper.properties needed to have LF line endings regardless of platform, in order to validate the distribution and wrapper SHA-256 sums on Windows. This PR fixes the all the issues at once by adding .gitattributes and upgrading Maven Wrapper to v3.3.2. Note that newer versions of Maven Wrapper don't even require the wrapper JAR or downloader source files.

This is my onboarding experience using Git Bash on Windows:

$ git clone https://github.com/AtomicJar/testcontainers-cloud-java-example

$ cd testcontainers-cloud-java-example

$ make test
bash: make: command not found

$ ./mvnw test
Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain
Caused by: java.lang.ClassNotFoundException: org.apache.maven.wrapper.MavenWrapperMain

And here is how it worked out after adding .gitattributes and upgrading Maven Wrapper to v3.3.2:
