Missing fields and improper placeholder values in Edit Post Modal.

[Anvita0305]

Describe the bug
While editing a post(Admin Role), the placeholders have OrgPostCard.postTitle1 instead of a proper text and fields image and video which are present in Create post modal, are missing in Edit post modal.

To Reproduce
Steps to reproduce the behavior:

1. Role: Admin
2. Create a post in your organization
3. Now if you want to edit it, for editing only 2 fields- title and information are present, not fields for editing image and video are present.
4. Also, the placeholder values are OrgPostCard.postTitle1 and OrgPostCard.information respectively for currently available fields.

Expected behavior

1. Placeholders must have text which can be easily understood by the user instead of OrgPostCard.postTitle1 and OrgPostCard.information.
2. User must also be able to edit image and video

Actual behavior

1. Unclear placeholder values
2. Missing fields in edit option
