Made "easy wins" copy-edit pass through vue components (#889)

Essentially scrubbed through .vue files in packages/editor-ui/src/components and copy edited labels/ tooltips etc.

Tried to prevent opinionated editing, simply rewriting existing meaning for clarity. I did however make an opinionated decision on changing a node's "Notes" to "Note" (only labels, nothing code related) because it feels more like a singluar note - especially when used as a subtitle in the workflow. Singular form also futureproofs functionality like showing a list of all node notes across a workflow (or versioning/ collaborative notes features).

So far, have gotten up to PageContentWrapper.vue (when sorted alphabetically). In a followup, will review ParameterInput.vue and onwards in /components folder

packages/editor-ui/src/components/CredentialsEdit.vue
