Remove "core: 8.x" from the .info.yml file

Hello Maintainers,
I have provided a patch to fix this issue.
Please review it.

Thanks!

Hello Harshita,

I have reviewed and implemented patch#2 provided by you.
The patch is implemented smoothly on my website having version -9.5 and PHP 8.1
There seems to be a slight change in core & Core version requirements. As the Drupal newer version >8 doesn't take core as in the info file.

And Thank you.

Modules, themes. and profiles are allowed to use the following lines in their .info.yml file.

core: 8.x
core_version_requirement: ^8 || ^9

That is described in New 'core_version_requirement' key in info.yml files for modules, themes and profiles → allows Composer semantic version constraints including specifying multiple major versions of core, which states:

For example a module that is compatible with Drupal 8 and Drupal 9 can have a info.yml file like this

name: My Module
type: module
core: 8.x
core_version_requirement: ^8 || ^9

There is no change that must be done in that .info.yml file.
