fix: removes unused polyfills from replace section

[kevin-kortum-trustedshops]

1. Why is this change necessary?

shopware5 has chosen to add polyfill replacements for libraries that are not used or not relevant to be replaced. While there is nothing wrong with it skipping polyfills, if there a package requiring it, there will be a conflict.

Considering #2853 there might be use cases where someone would like to add shopware5 as a dev requirement, but will fail if there is conflicts due to the polyfill. Although time has told that this is very unlikely (or was never reported) the docs of symfony/polyfill https://github.com/symfony/polyfill?tab=readme-ov-file#design recommend only to replace them if provided by the package or if they can safely be skipped e.g. of an unsupported php version.

2. What does this change do, exactly?

Instead of not installing polyfills, it will not install those into the vendor directory. For PHP 7.4 it will increase the vendor directory by ~33% (42 MB) as for PHP 8.2 only by ~0,12% (2 MB).

3. Describe each step to reproduce the issue or behaviour.

Please refer to composer/composer#12412 .

4. Please link to the relevant issues (if any).

#2853

5. Which documentation changes (if any) need to be made because of this PR?
