429 Too Many Requests

[Lohann]

Describe the bug
Getting this error consistently from deno, I frequently need to Reload Window because typescript LSP simply gets confused very often when working using workspaces.

I get following error, one per deno.json in the workspace:

[{
	"resource": "/Users/<username>/path/to/<project>/deno.json",
	"owner": "_generated_diagnostic_collection_name_#1",
	"code": "768",
	"severity": 4,
	"message": "Unable to load schema from 'https://raw.githubusercontent.com/denoland/deno/main/cli/schemas/config-file.v1.json': HTTP status code 429\n429: Too Many Requests\nFor more on scraping GitHub and how it may affect your rights, please review our Terms of Service (https://docs.github.com/en/site-policy/github-terms/github-terms-of-service).",

}]

To Reproduce

I have a open-source project using deno workspaces, it has 3 modules:
https://github.com/Lohann/merkle-patricia-trie-demo

Settings at .vscode/settings.json:

{
    "deno.enable": true,
    "deno.maxTsServerMemory": 16384,
    "deno.path": "/opt/homebrew/bin/deno"
}

Expected behavior
Deno extension must cache the config-file.v1.json file, it never changes anyway.
