[TASK] Raise dependency egulias/email-validator to ^3.2.1

This patch raises egulias/email-validator to min version of
3.2.1, which incorporates latest changes. This also contains
a fix to avoid the usage of PHP8.2 deprecated methods, namely
`utf8_encode()` and `utf8_decode()`.

Used commands:

> composer req egulias/email-validator:"^3.2.1"
> composer req egulias/email-validator:"^3.2.1" \
    -d typo3/sysext/core --no-update
