compute: support alphanumeric build names in fedoraImage diff suppress regex [advanced]

[shuyama1]

Resolves acceptance test failure TestAccComputeDisk_imageDiffSuppressPublicVendorsFamilyNames.

The regular expression fedoraImage previously only matched numeric digits ([0-9]+) for the 4th version component of Fedora CoreOS image names. Newer Fedora CoreOS images (e.g. fedora-coreos-43-20260411-20-dev0-gcp-aarch64) include alphanumeric build tags (e.g. dev0). This update allows fedoraImage to match alphanumeric build tags.

Fixes hashicorp/terraform-provider-google#28424
