Description

In JsonPath, the compact dot notation for segments is a shortcut making it easier to access keys that can be written as an identifier. The canonical form is to use the bracket notation with the property name as a (quoted) string: https://www.rfc-editor.org/rfc/rfc9535#name-segments

However, our JsonPath class building an expression is always using the dot notation, without checking that the provided keys is a valid identifier.

How to reproduce

use Symfony\Component\JsonPath\JsonCrawler;
use Symfony\Component\JsonPath\JsonPath;

$jsonPathExpression = (string) (new JsonPath)->key('some-prop');

dump((new JsonCrawler('{"some-prop": "example value"}'))->find($jsonPathExpression));

Possible Solution

We should either always use the bracket notation or select the notation based on the key.
