Bumps guzzlehttp/guzzle from 7.8.1 to 7.12.1.

Sourced from guzzlehttp/guzzle's releases.

7.12.1

Changed

• Adjusted guzzlehttp/psr7 version constraint to ^2.12.1

Fixed

• Reject proxy URLs with a malformed scheme in the cURL handlers instead of letting libcurl mishandle them

Security

• Reject HTTPS proxies when the installed libcurl lacks HTTPS-proxy support (GHSA-wpwq-4j6v-78m3)
• Reject dot-only cookie Domain attributes as match-all (GHSA-cwxw-98qj-8qjx)

7.12.0

Added

• Added RequestOptions constants for curl, retries, and stream_context

Changed

• Adjusted guzzlehttp/psr7 version constraint to ^2.12
• Constrain cURL transport sharing to safe libcurl DNS and SSL session support
• Resolve proxy environment variables in the cURL handlers; libcurl no longer reads the environment itself
• Ignore proxy environment variables when the proxy request option makes a decision
• Disable proxy environment variables on Windows SAPIs other than CLI (httpoxy hardening)
• Redact proxy credentials from cURL handler error messages, following Psr7\Utils::redactUserInfo()
• Normalize no-proxy domain and IP literal matching across the cURL and stream handlers

Deprecated

• Deprecated the request-level handler option, which will be ignored in 8.0
• Deprecated raw cURL request options outside the built-in cURL handlers' allow-list
• Deprecated the CURLOPT_PROXYTYPE cURL request option; set the proxy type via a scheme-prefixed proxy URL
• Deprecated PHP stream context options outside the built-in stream handler allow-list
• Deprecated passing ntlm as a built-in auth type
• Deprecated Utils::describeType()
• Deprecated non-finite floats in the query and form_params options; 8.0 rejects them
• Deprecated non-string scalar values in the body option; 8.0 rejects them

Fixed

• Fix cURL TLS and HTTP/2 capability detection using libcurl feature checks
• Fix proxy no list matches being re-proxied through environment-configured proxies by libcurl
• Fix no list and NO_PROXY matching to support IP CIDR ranges, matching libcurl
• Fix the stream handler not applying scheme-less proxies and their credentials

7.11.2

Fixed
