The items in the “bulb menu” are called Code Actions or Quick Fixes (see this documentation).
A code action represents a change that can be performed in code, e.g. to fix a problem or to refactor code.
The VSCode extension API docs provide more context on how extensions can provide Code Actions here. A Code Action can provide a WorkspaceEdit to perform (to amend the text the user entered, for example), or it can provide a Command to run for more complex actions.
