Pressing tab on a opened multiple select input causes a error

[Jack Davies]

Current Behaviour 😯

Pressing tab on a opened multiple select input causes the error
MUI: The "value" prop must be an array when using the "Select" component with "multiple".

Expected Behaviour 🤔

Pressing tab on a opened multiple select input should close the dropdown and navigate to the next input

thanks for the report @jockjocko

It's caused by this workaround: https://github.com/stackworx/formik-mui/blob/main/packages/formik-mui/src/Select.tsx#L52

Not sure how best to fix it...
