cURL 8.1.0 `URL using bad/illegal format or missing URL` for URL starting with digit

[PkAIR]

With latest release of cURL 8.1.0 now it impossible to use it for get/put requests with URLs starting with digits.

I did this

curl http://10.xxx.xxx.xxx/composer/packages.json

I expected the following

File was downloaded but got URL using bad/illegal format or missing URL

curl/libcurl version

cURL 8.1.0

operating system

Latest Alpine docker image

My apologies.

This regression is considered important enough to warrant a follow-up patch release. 8.1.1 is now due to ship on May 23, 2023. Stay tuned. We will also merge other bugfixes that are ready to include in this release.
