feat(tracing): Add GB unit to device memory tag value (#4935)

dashed · web-flow · commit f67b1c2682ec · 2022-04-14T12:41:34.000-04:00
Since tag values are always strings, it'll be useful to attach units to the `deviceMemory` tag. Since `navigator.deviceMemory` are approximate in gigabytes, we can suffix the tag value with " GB". Reference: https://developer.mozilla.org/en-US/docs/Web/API/Navigator/deviceMemory
