New version of tfx cli 0.21.0 publish does not work on Azure DevOps Server

[Banner-Keith]

I have tried this against these versions:
Azure DevOps Server 2022.0.1 (AzureDevOpsServer_20231109.3)
Azure DevOps Server 2022.2 (AzureDevopsServer_20250213.1)

I use this publish command. Redacted the url, pat, and extension path
tfx extension publish --service-url https://tfs.example.com --auth-type pat --token **** --vsix **** --no-wait-validation

When publishing an extension with 0.21.0 I get this error back:

error: No MediaTypeFormatter is available to read an object of type 'ExtensionPackage' from content with media type 'application/octet-stream'

I reverted back to 0.20.0 and it worked with that version.

I can confirm this issue, affects all current versions of DevOps Server - verified with DevOps Server Update 2 Patch 1 - 3:

AzureDevopsServer_20240702.1
AzureDevopsServer_20241028.1
AzureDevopsServer_20250224.1

Started happening this week in YML Pipeline using Microsoft "Extension Publish Task" (tried both V4 and V5). Internally both just call the Tfx-Cli Command Line interface, so the current workaround was to force installation of 0.20.0 in the "Use Node CLI" Task.

Hi! I've identified the problem as a limitation in Azure DevOps Server. The issue was introduced in #494.

One potential fix is available in #504.
