Not finding digest

[thompson-tomo]

In a rust project () I contribute to we are using dist to build our distributions. This library generates it's own workflow file to support the release. This file can be customised in a couple of ways:

• importing steps
• defining pinned versions to use by the system.

Both of which we use hence I have attempted to manage these dependencies via a custom manager but have had no luck due to the digest. After a few attempts I am still getting

Could not determine new digest for update

My config is https://github.com/open-telemetry/weaver/blob/main/.github/renovate.json5 with the key part being:

{
      customType: "regex",
      description: "Update Cargo Dist Actions",
      managerFilePatterns: [
        "dist-workspace.toml",
      ],
      matchStrings: [
        "\"(?<packageName>.+\/?)\" = \"(?<currentDigest>[a-f0-9]{40})\" # v(?<depVersion>[0-9.]+)"
      ],
      datasourceTemplate: "github-releases",
      versioningTemplate: "semver",
      currentValueTemplate: "{{depVersion}}",
      extractVersionTemplate: "^v(?<version>.*)$",
      autoReplaceStringTemplate: "\"{{depName}}\" = \"{{newDigest}}\" # v{{newVersion}}",
      depTypeTemplate: "action",
    },
    {
      customType: "regex",
      description: "Update Cargo Dist Yaml Actions",
      managerFilePatterns: [
        ".github/build-setup.yml",
      ],
      matchStrings: [
        "uses: (?<packageName>.+?)@(?<currentDigest>[a-f0-9]{40}) # v(?<depVersion>[0-9.]+)"
      ],
      datasourceTemplate: "github-tags",
      versioningTemplate: "semver",
      currentValueTemplate: "{{depVersion}}",
      extractVersionTemplate: "^v(?<version>.*)$",
      autoReplaceStringTemplate: "uses: {{depName}}@{{newDigest}} # v{{newVersion}}",
      depTypeTemplate: "action",
    },

I am aware that different data sources are being used but neither work.

The following pr shows the issue open-telemetry/weaver#1226 with the CI being resolved if the first manager worked.

I know it is correctly detecting the dependencies but in the file mentioned in the custom manager but the digest is causing issues.
