RFR: 8366278: Form control element <select> has no associated label

[Pasam Soujanya]

Associating a meaningful label with every UI control allows the browser and assistive technology to expose and announce the control to a user. Associating a visible label also provides a larger clickable area.

`<select id="search-modules">` should contain a label or title to describe it's purpose.
