Description of problem:

In various IDP forms in OCM UI, the "Browser" and "Cancel" buttons for file upload section seems like overlapped or attached. It create a bad visual experience and UX. Probably a white space between each buttons would make better visual experience.

How reproducible:

always

Steps to Reproduce:

1. Open OCM UI staging 
2. Open a ready OSD/ROSA cluster.
3. Go to "Access control" tab > Identity provider section
4. Select "GitLab" IDP 
5. See the "CA file" field and button definitions.

Actual results:

Look and feel of "Browse" and "Cancel" button seems like overlapped in the IDP forms (ex: Gitlab IDP section)

Expected results:

Improve the visual experience of these buttons by including white space to separate each other.
