Feat/register phpinfo entries

[henderkes]

closes #2576

Edit: the entries are sorted now.

@dunglas I know you've worked on the watcher-go library before, perhaps you could expose a proper version number instead?

[henderkes]

@dunglas I think we should revert the last commit and make not passing the nobrotli tag a build error when libbrotli isn't available. It would shift the runtime error to a compile time error.

[dunglas]

For watcher, this is because of e-dant/watcher#102

[dunglas]

Many other modules can influence what FrankenPHP does. I wonder if we should just list all installed modules, with their versions. It's verbose, but it covers all use cases and is practical to debug.

[henderkes]

I've thought about it, but I can't really see a use-case for it. It would just clutter away the information we can really influence.

[dunglas]

FrankenPHP extensions, Prometheus-related modules. Actually, even the exact go version matters (HTTP stdlib behavior sometimes change). Maybe could we hide this by default in a <details> HTML element?

[henderkes]

@dunglas I'm not sure if we really should rename AddPhpinfoEntry to AddPHPInfoEntry. Phpinfo refers to the phpinfo() function to print this.

[dunglas]

I'm not sure either but this sounds more idiomatic to me. People who will call this function will do it in Go, it in PHP.
