Add Note Prop To Select And MultiSelect Components

[pharv]

• Adds note prop to Select and MultiSelect component, which displays secondary text for each dropdown menu item (right-aligned, light gray)
• Fixes bug in MultiSelect where menu items do not get updated if the items prop changes
• Locks dependency for react-table package at v6.8.6 because later versions break the checkbox table component
• Removes yarn.lock file from source control so that dependency issues like the previous one can be discovered
