Incorrect detection of SBOM SPDX manifest as sendgrid secrets

[BernieWhite]

When using vsce package command, errors are returned for manifest.spdx.json files claiming they are Send Grid secrets, however they are just hashes as per SPDX SBOM spec.

Example file with false positive: https://www.powershellgallery.com/packages/PSRule.Rules.Azure/1.41.0/Content/_manifest%5Cspdx_2.2%5Cmanifest.spdx.json

Seems to be an issue with secretlint which we use for scanning secrets, I created an issue upstream and provided a PR to fix the issue.
