Symfony version(s) affected: 4.4.0

Description

XmlDumper doesn't preserve container parameter types.
Use any numeric-like parameter in container parameter value leads to have loaded value type float|int from xml cache.

How to reproduce

Use parameter with value something like '+1238523'.
Expected loaded value: string(8) "+1238523"
Actual loaded value: double(1238523)
