"Stream 49 cancelled" error on multi-module Maven projects

[tmielke]

I came across this plugin recently and find it very useful.
However, when using it on a multi-module Maven project, it typically fails within a few seconds with an error like

[ERROR] Failed to execute goal com.giovds:outdated-maven-plugin:1.4.0:check (default-cli) on project XXX: Failed to connect.: Stream 49 cancelled -> [Help 1]

The stream number (49 in this example) differs each time.
E.g. when trying it on the Apache Camel project, I never get it to complete successfully.

The full call stack of the error reads:

[ERROR] Failed to execute goal com.giovds:outdated-maven-plugin:1.4.0:check (default-cli) on project XXX: Failed to connect.: Stream 49 cancelled -> [Help 1]

I asked AI tools to help and fix the error and the code changes suggested seem to make the plugin work on large multi-module projects like Apache Camel.
Suggested changes were to switch from HTTP/2 to HTTP/1.1 for easier resource management but also to add retries and timeouts.
I would be happy to submit a PR but it will need some proper review, as I am less familiar with the codebase of this plugin.

I'm happy to review PR's. I'm currently very busy and need some personal time off so this has been put on the backlog for me.

Thanks @Giovds, I submitted my changes in #188 .
As this code is mostly AI generated, it should get a proper review.
But with these changes applied I am able to run the plugin over 480+ Maven submodules in one go, without any execution errors like the one reported here.

@tmielke Thanks for the contribution! I think with some final tweaks this should be a nice low impact yet great feature.

I have also put Copilot to work for some initial comments. Though I don't agree with all his suggestions, I think it is worth looking at (especially the exception handling).

I've put my thoughts as comment on the PR.
