Fix false positive where GitHub Actions subject was not recognized

[prdngr]

Hi, this PR fixes a false positive in cape and role-trusts. In situations where the AWS trust policy of a GitHub Actions OIDC role verifies the sub claim, as shown below, CloudFox reported the trusted subject as "ALL REPOS!!!".

"Condition": {
    "ForAllValues:StringLike": {
        "token.actions.githubusercontent.com:sub": "repo:BishopFox/cloudfox:*"
    },
    [...]
}
