Allow to hide/show attributes

[joanagmaia]

Changes proposed ✍️

• Add show/hide button next to attribute's field -> Only render the button if attribute cannot be deleted
• Once the button is clicked, the user is prompted with a message to confirm their action. Once the action is confirmed, the attribute will either be shown/hidden from member's profiles
• Fix Attributes section in New members -> The filtering for custom attributes was throwing an error for new member form, because there was no record. For new members form it will only be shown attributes that can be deleted. For edit form, all member's attributes will be displayed
• Refactor get-custom-attribuetes so that show property can be considered or not when filtering depending on the use case. For members filters (considered), for forms (not considered)

The code and functionality look great!

A couple of suggested changes:

• I think the eye icon is mixed up. Notion has the "on" eye when the attribute is visible and the off eye when it is not. I think that makes more sense. When I visited a member for the first time, it looked like all attributes were hidden.

• I would grey out the icon when it is hidden, to give more visibility (see the notion screenshot).

• I would make the icons a bit smaller, and the default a bit lighter, but this is more personal preference 😀

• I think that the Hidden subtitle adds some value in Notion, I would suggest to add it.
