[docs] Broken `google_scc` docs

[colleenmcginnis]

In the Google Security Command Center integration (added in #6645), the description of the google_scc.finding.access.service_account.delegation_info.principal.subject field has an unclosed {, which is breaking the docs build. No integration docs updates will be published until this is resolved here and the changes are available on EPR.

integrations/packages/google_scc/data_stream/finding/fields/fields.yml

Line 45 in b845b1d

description: A string representing the principalSubject associated with the identity. As compared to principalEmail, supports principals that aren't associated with email addresses, such as third party principals. For most identities, the format will be principal://iam.googleapis.com/{identity pool name}/subject/{subject) except for some GKE identities (GKE_WORKLOAD, FREEFORM, GKE_HUB_WORKLOAD) that are still in the legacy format serviceAccount:{identity pool name}[{subject}].

To fix this, this part of the description needs to be updated:

- principal://iam.googleapis.com/{identity pool name}/subject/{subject)
+ principal://iam.googleapis.com/{identity pool name}/subject/{subject}

@piyush-elastic @janvi-elastic can we get this addressed ASAP as it's blocking all new integration docs for being published.
