Remove unwanted list style bullets from dropdown menus

After the PF5 upgrade, older components using PF4 dropdown menus had list style bullets appear for unordered lists

Metrics Plugin still uses PF4 components and styling

PatterFly removes list-style bullets or numbers from the <ul>/<ol> elements by default and then adds them where needed. 

The OCP console chose to override this because of the amount of <ul>/<ol> elements in our codebase that expect the default bullet or numbers to be present.
