If the target website has a Chinese domain name, it will not be able to match.

### Steps To Reproduce

1. Go to https://中文.tw/

### Expected Result

match

### Actual Result

not match

### Screenshots or Videos

_No response_

### Additional Context

I manually changed it to `https://xn--fiq228c.tw/`

Matches are working now.

It's not easy for people to directly convert these types of domain names into domain names starting with "xn", so it should be necessary to directly support the input of such domain names.

### Issue Tracking Info

- [x] I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Start by reproducing the mismatch at https://中文.tw/ in the affected Bitwarden client and compare it with the manually converted https://xn--fiq228c.tw/ URL. Trace the website-matching flow to identify where internationalized domain names are handled; done means the original Chinese domain matches without manual conversion.
