[Schema Inaccuracy] remove redundant space in curl code examples which prevents copying and using the sample as-is

[cmwilson21]

This is being copied from the open source repo, PR 19442
(Automation in rest-schema label did not copy it over)

Schema Inaccuracy

• Go to any page showing a code sample (e.g. this page)
• Click on the "cURL" tab
• Copy the sample (either by clicking on the copy button, or selecting and copying the code sample)
• Paste the code sample in a terminal and run it

Expected

cURL command will run and return an error (e.g. bad credentials)

Actual
cURL command does not run properly and is split to 2 separate commands:

$ curl \
>   -H "Accept: application/vnd.github+json" \ 
curl: (3) URL using bad/illegal format or missing URL
$   -H "Authorization: token <TOKEN>" \
>   https://api.github.com/user/repository_invitations
-H: command not found

Hi @cmwilson21.

Any progress on this? The changes made by Ori Hoch back in PR 19442 can be pretty much merged as they are.

To corroborate his findings, here is ShellCheck's output after pasting one of the affected Code Samples in it:

And here's the full ShellCheck documentation for the error, for a more detailed report.
