[TASK] Temporarily workaround a missing conflict in symfony/type-info

[bnf]

symfony/type-info is currently not compatible to phpstan/phpdoc-parser 2.x which results in a PHP error in extbase modules as shown in https://forge.typo3.org/issues/105582. A fix has been merged upstream, but has not been released yet and it seems there will be no immediate hotfix release by symfony – that means it will only be released by the end of the month [2]).

Explanation of the issue:

phpdocumentor/reflection-docblock 5.6.0 [1] was released yesterday which allows composer install and composer update to raise phpstan/phpdoc-parser to 2.x.

Since symfony/type-info has an optional dependency to phpstan/phpdoc-parser, a conflict is used to express the supported version. This upstream conflict has a weak range [3] as it only forbids incompatible old versions, but not new upcoming major(!) versions.
The statement "conflict": "<1.0"[3] forbids to install any version before 1.0, but missed to opt out from future major releases (which are allowed to be breaking per semver).

Now that phpstan/phpdoc-parser 2.x has been released and is allowed to be installed by other dependencies like
phpdocumentor/reflection-docblock (which is perfectly fine), this range flaw got revealed.

This workaround will be removed once symfony/type-info has been updated to allow an upgrade to phpstan/phpdoc-parser. For that reason this conflict is only added to this composer-only package to avoid a comlete TYPO3 release and is not added to extbase (extbase is not incompatible, symfony/type-info is).
