Fixes Pipeline list commit column width should be adjusted

What does this MR do?

• Fixes some HTML problems
  • Pipeline and Build tables were inside an ul tag
  • Pipeline table had 2 tbody tags and no thead
• Adds grid classes in Pipeline table in order to be responsive: The content of the last column was being hidden but the column it self was not which results in a lot of blank space
• Adds a percentage width to the commit column in the Pipeline table.
• Removes one level of nesting in the commit column in the Pipeline table and to the Build column in the Build table.
