[v6] Getting all keys of searchParams

[bar-boko]

React Router in v6 added the full support for managing the search parameters from the URL (a.k.a the part in the URL, which starts after ? and followed by pairs of key=value divided by & signs).

The main problem with the current API of searchParams is the ability to change a specific searchParam, without changing the rest of the parameters.

For example:

• From /search?a=aaaa&b=b&c=c
• To /search?a=a&b=b&c=c

Now it can be done by very a weird way:

const [searchParams, setSearchParams] = useSearchParams();

searchParams.set('a', 'a');
setSearchParams(searchParams.toString());

Is there any way to simplify this case?
