Description

When adding dependabot for terraform repositories with multiple nested directories:

• Dependabot will not look recursively through all directories for .tf files. And this prevents submodules from getting updates
• Also, in a repo where there are multiple directories, will result in having to create dependabot entries for every single directory which result in a very long file. It would be nice if we can implement a feature to use glob patterns or to provide multiple paths to dependabot directory so that it will pick the .tf files in the nested directories.
