PHP version error when installing other extensions

[VivekShingala]

Hi,

We have a Magento 2.3.1 store running on PHP 7.2.20 and this blog module installed on it.
However, when we try to install a new extension on Magento setup, it gives below error.

Your requirements could not be resolved to an installable set of packages.

Problem 1
- Installation request for mirasvit/module-blog 1.0.5 -> satisfiable by mirasvit/module-blog[1.0.5].
- mirasvit/module-blog 1.0.5 requires php ~5.5.0|~5.6.0|~7.0.0 -> your PHP version (7.2.20) does not satisfy that requirement.

For Magento 2.3.1, we need php 7.1.3 or higher.
Supported PHP versions:
~7.1.3
~7.2.0
