List of changes:

• Delete forced font 'Hind Siliguri' on autocomplete select menu.
• Change font on StyledCreatableSelect to match the header instead of the body.

Type of change:

• [x] Bug fix (non-breaking change which fixes an issue)

How to test:

• Find any select menu on any page and check if it's font matches with it's labels font.

Questions:

• The font 'Hind Siliguri' was hard-coded on the autocomplete select menu so was it an intentional design decision?
• The header and body font themes are different. So again was the different font on the select menu an intentional design decision?
