Lines starting with **

[stek29]

If line in .gitignore already starts with **, then gitignore-to-dockerignore emits **/**, which should be just **.

Steps to reproduce:

echo "**/*.o" > .gitignore
gitignore-to-dockerignore
cat .dockerignore

Expected:

.git/
**/*.o

Got:

.git/
**/**/*.o

Workaround is just:

  gitignoreToDockerignore(dotGitignore).replace(
    /\*\*\/\*\*\//g,
    "**/",
  );
