Add info button to selected phenotypes

Tooltip info-circle placeholder has been added to the HPO phenotypes in the summary, but I cannot continue working on this issue due to a larger task that came up.

TO DO:

• Check that the hover-text for the info-circle is working correctly, it was behaving weirdly for me.

• Make the info-circle a button that loads the pop up of the details about the phenotype that it is next to. See the phenotype info-circle buttons in the Clinical Symptoms section of the form to find the code that does this.

• Fix the spacing of the info-circle, ie. make the space between the phenotype and circle smaller and the space between the circle and Add Details/Delete buttons larger.
