HttpParams instantiation using fromObject option with number or boolean parameters does not convert them to string #42641
Description
Bug Report
Affected Package
The issue is caused by package @angular/common/http
Is this a regression?
No
Description
From Angular version 12, the HttpParamsOptions allows number and boolean types in fromObject, introduced with commit #40663
When a new HttpParams object is created using that option, then the parameters are not converted to string, so when using the get and getAll methods the value does not match the expected string | null type.
This causes type errors and tests failing.

Minimal Reproduction
const params = new HttpParams({ fromObject: { numericParam: 5 } });
console.log(
typeof params.get('numericParam') === 'number', // true
params.get('numericParam') === '5', // false
// params.get('numericParam') === 5, // does not compile
);
