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

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

Thanks!

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.

@Harshita mehna, I see you have opened several issues in the last few days. All novice, and most unnecessary.

The amount of issues you have posted in the last few days leads other contributors to think you may be attempting to gamify the Drupal attribution system.
