[Security] Bump sprockets from 3.7.1 to 3.7.2

[dependabot-preview]

Bumps sprockets from 3.7.1 to 3.7.2. This update includes a security fix.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Path Traversal in Sprockets Specially crafted requests can be used to access files that exist on the filesystem that is outside an application's root directory, when the Sprockets server is used in production.

All users running an affected release should either upgrade or use one of the work arounds immediately.

Workaround: In Rails applications, work around this issue, set config.assets.compile = false and config.public_file_server.enabled = true in an initializer and precompile the assets.

This work around will not be possible in all hosting environments and upgrading is advised.

Patched versions: >= 2.12.5, < 3.0.0; >= 3.7.2, < 4.0.0; >= 4.0.0.beta8 Unaffected versions: none
