Remove deprecated 'php-http/message-factory' dependency

[Bombaninha]

Description:

This PR closes #1441

Removed the dependency on php-http/message-factory from the composer.json file.

This update is aligned with the ongoing trend of deprecating php-http/message-factory in favor of psr/http-factory to ensure compatibility with modern libraries and to avoid using deprecated components.

Evidence Collected from Other Package Changelogs:

• nyholm/psr7

Make dependency on php-http/message-factory optional.

• php-http/message

Removed dependency on php-http/message-factory as it is abandoned and this package does not actually use it.

• php-http/discovery

Dropped php-http/message-factory from composer requirements as it is deprecated in favor of PSR-17.

• php-http/mock-client

Removed dependency on php-http/message-factory as the mock client does not use it.

Hello, @ezimuel. Thanks for your feedback!
Do you have a target version for this change? I was thinking of keeping it in the latest (main).
Regarding the rebase onto main, I already get "up to date."

@Bombaninha you need to use main branch. Try to merge from main of the original repository (https://github.com/elastic/elasticsearch-php):

• git fetch upstream where upstream is the original repository (https://github.com/elastic/elasticsearch-php)
• git merge upstream/main

Done, @ezimuel.
Let me know if everything looks good or if there's anything else I should adjust.
Thanks!

LGTM, thanks!
