Since v0.56.4, touch terragrunt.hcl causes init to run despite no other changes (possibly introduced by provider cache option)

[lorengordon]

Describe the bug

init is running every time I touch the terragrunt config, even though nothing has actually changed.

Steps To Reproduce

1. Install terragrunt v0.56.3
2. Run plan
3. touch terragrunt.hcl
4. Run plan.
5. See init does not run on the second plan
6. Install terragrunt v0.56.4
7. touch terragrunt.hcl
8. Run plan
9. See init runs despite no changes needing init to run
10. Repeat with terragrunt v0.58.3 to confirm problem still on latest version

Expected behavior

init should not run unless it needs to.

Versions

• Terragrunt version: v0.56.4-v0.58.3
• OpenTofu/Terraform version: Terraform 1.5.6
• Environment details (Ubuntu 20.04, Windows 10, etc.): WSL/Ubuntu 22.04

Additional context

v0.56.4 introduced the Terragrunt Provider Cache, so that's my first suspect for this new behavior...
