K8SPS-469 fix data-at-rest tests

[pooknull]

DESCRIPTION

Problem:
Restores fail on clusters with specified .spec.mysql.vaultSecretName

Cause:
xtrabackup started outputting an additional line when the command xtrabackup --version is executed:

bash-5.1$ xtrabackup --version
2025-10-08T13:35:51.700206-00:00 0 [Note] [MY-011825] [Xtrabackup] recognized server arguments: --datadir=/var/lib/mysql
xtrabackup version 8.4.0-4 based on MySQL server 8.4.0 Linux (x86_64) (revision id: c584cb20)

The run-restore.sh script uses this command to determine the xtrabackup version.
Previously, it expected output such as 8.0 or 8.4, but now it receives an additional line, resulting in:

[Note].
8.4

Solution:
Extract the line containing the xtrabackup version prefix and parse the version from that line

Pull Request Overview

Fixes restore failures on clusters with specified .spec.mysql.vaultSecretName by updating the xtrabackup version parsing logic to handle additional output lines that were introduced in newer xtrabackup versions.

• Updated version parsing to filter for the specific "xtrabackup version" line before extracting version numbers
• Ensures compatibility with xtrabackup's new output format that includes additional log messages
