t() calls should be avoided in classes

Hello,

I have created a patch to solve the issue related to t() calls .

Please review and apply it .

@Prachii, Your Merge Request is empty. Please re-view it. Thanks

@Prachi,
a) I have reviewed the code in the patch. By using $this->t() instead of t(), you ensure that the translation is handled correctly within the Drupal ecosystem. The $this->t() method is aware of the current context and can apply the appropriate translation logic, such as using the active language and considering the translation settings of the site.

I am creating MR! for your patch.

Your Patch is good to go. And Thank you.

Thank you @Raveen Thakur for reviewing my patch.
