Setter property with `[<Erase>]` should be erased

[MangelMaxime]

Description

While working on #3929, it seems like some cases have not been covered.

This code

[<Erase>]
type internal LanguageInjectionAttribute() =
    inherit Attribute()
    
    [<Erase>]
    member val Prefix = "" with get, set

does not generate the getter but does generate the setter function:

export function LanguageInjectionAttribute__set_Prefix_Z721C83C5(__, v) {
    __["Prefix@"] = v;
}

Repro code

Please provide the F# code to reproduce the problem or a link to the REPL.
Ideally, it should be possible to easily turn this code into a unit test.

Expected and actual results

Please provide the expected and actual results.

I was checking this problem a bit and probably this isn't a Fable problem but FSharp compiler issue.

When I ran the attached code in the example, FSharp compilation result did not add attribute to set_prefix while it does for get_prefix

Tested with dotnet 8.0.403 on the latest main branch.

It seems like I found a way to find the attributes information somewhere else for this situation, waiting for confirmation before implementing it.
