fix: Table builder Browser column overrides parent module field

[zeezo887]

Description

This PR overrides the base TableColumn class getKey() to prepend the browser's name to the browser key.

public function getKey(): string
    {
        if ($this->key === null) {
            throw new ColumnMissingPropertyException();
        }

        if (null === $this->browser) {
            throw new ColumnMissingPropertyException('Browser column missing browser value: ' . $this->field);
        }

        return "$this->browser.$this->key";
    }

Isn't it possible for two browsers to also have the same name?

[zeezo887]

Browsers can use the same module, but cannot have the same name within the same form.
