[BUG] PR decoration fails randomly

Describe the bug

Sometimes, the PR decoration - supposed to happen when running the action on a PR - fails and the Checkmarx comment on the PR is not created (or updated).

(This is run from GitHub hosted-runner so there's no issue of enterprise network/vpn).

Expected behavior

The PR should be commented with the Checkmarx result.

Actual behavior

The Checkmarx comment on the PR is sometimes not created/updated after the Checkmarx scan and we need to consult the acton logs to see the scan results.

The corresponding scan logs indicate the relevant lines:

Creating PR decoration for scan ID: xxxxxxxxx-xxxxxxxxxxxxxxx-xxxxxxxxxxxxxxx Post "https://eu.ast.checkmarx.net/api/flow-publisher/pr/github": context deadline exceeded (Client.Timeout exceeded while awaiting headers)

Steps to reproduce

Sadly random.

Additional comments

If the the Checkmarx server is unreliable (as it sadly appears to be, considering how often this fails) when trying to publish the PR result, it should be mitigated, for example with some kind of retry mechanism? (despite the 'Request attempt 1 in 4' log followed by a failure, there doesn't seem to be any second attempt)
