Arr Widget - timezone with quotes doesn't work properly

### Widget link

widgets/arr-releases-by-erkston

### Description

`timezone: "-04" # must have quotes`

this would only work for if i didnt add quotes

i.e

`timezone: +0930`

Start with the widgets/arr-releases-by-erkston widget and reproduce the timezone configuration using both the quoted "-04" value and the unquoted +0930 value. Trace how each value is parsed; done means quoted timezone offsets work correctly without breaking the existing unquoted format.
