fix: added extra condition in isBrowser function

[ignaciosantise]

Description

• Added an extra condition to isBrowser function as the current one is not enough for react native.
  • getNavigator returns {"product": "ReactNative"}, and getDocument returns undefined

The origin of the issue is here:

walletconnect-monorepo/packages/utils/src/misc.ts

Lines 406 to 407 in 91af38e

	if (!isBrowser()) return;
	return localStorage.getItem(key) as string;

because localStorage.getItem is executed in a RN environment

Another option is to change the isBrowser condition to something that also covers react native, such as

if (!isBrowser() || isReactNative()) return;

Type of change

• Chore (non-breaking change that addresses non-functional tasks, maintenance, or code quality improvements)
• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Draft PR (breaking/non-breaking change which needs more work for having a proper functionality [Mark this PR as ready to review only when completely ready])
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

How has this been tested?

Tested locally in react native
