Fix Dependabot removes double backslashes in maven plugin configurations

[mallowlabs]

Problem

Dependabot removes backslashes in maven pom.
This PR will fix it.

Example PR: mallowlabs/dependabot-maven-double-backslashes-test#1

Reason

String#gsub escapes double backslashes.
Using block prevents this problem.

irb(main):001:0> "\\\\".gsub("\\\\","\\\\")
=> "\\"
irb(main):001:0> "\\\\".gsub("\\\\") { "\\\\" }
=> "\\\\"

Background

I use spotless-maven-plugin.
The importOrder configuration contains \\#.

Thanks for including a test with this PR.

I've got a queue of PR's I'm trying to deploy/merge the next day or two, but will try to get this landed soon.

Looks like there's a lint issue, can you fix?
