Backport of #25243

Original PR: #25243 — fix(coderd/azureidentity): add Azure IMDS G2 chain certificates
Merge commit: 49c6191

Backport of #25243

Azure IMDS attested data signatures can now chain through
Microsoft TLS G2 RSA CA OCSP intermediates, then through the
cross-signed Microsoft TLS RSA Root G2 certificate, before reaching
DigiCert Global Root G2.

coderd did not bundle the new G2 OCSP intermediates or the
cross-signed Microsoft TLS RSA Root G2 bridge certificate, so it could
fail to build a trusted chain for affected IMDS signatures.
