User profile edit button missing link purpose

2.4.4 Link Purpose (in context)
The pencil icon next to the Personal Information in the profile page does not have a link purpose because it lacks a link text. People with a screen reader will hear [link] but they will not hear the purpose of this link. This can be resolved by adding a description between the anchor tags (<a> </a>).
