Numeric named parameter overwrites plural parameter in pluralization

[netpok]

Reporting a bug?

When using the following code a numeric named parameter overwrites the plural parameter:

t('Test', plural, { named: {n: namedValue}})

It looks like somewhere the following happens:

if (named.n is number) {
  plural = named.n
}

Expected behavior

When the Test translation key is set to one|{n} the following is expected/happens:

plural	namedValue	expected	current output
1	1	one	✅ one
2	2	2	✅ 2
1	2	one	❌ 2
2	1	1	❌ one
1	string	one	✅ one
2	string	string	✅ string

Reproduction

If the table above is not enough I will create a repo.

No response

Additional context

In my opinion the n and plural variables should not be used for different things but I still consider this as bug.
