Ruslan Aliev 76d8716968 Replace become: true notation
Ansible documentation recommends to use yes/no as boolean value,
the last mention of possible using true/yes related to version 2.4 [1].
Starting from version 2.5 only become: yes specified in docs [2][3].
Since we have both variations, this patch aligns become statement to
use only yes value.
