Configuration kspWebMainMetadata missing

In project are declared
**targets**: JS, WasmJS
**sourceSets**: commonMain, webMain
## Gradle tasks are correct:
```
kspCommonMainKotlinMetadata
kspKotlinJs
kspKotlinWasmJs
kspTestKotlinJs
kspTestKotlinWasmJs
kspWebMainKotlinMetadata
```
## But in configurations are:
```
ksp
kspCommonMainMetadata
kspJs
kspJsTest
kspWasmJs
kspWasmJsTest
```
-> ``kspWebMainMetadata`` is missing

## I found only one way how to use task "kspWebMainKotlinMetadata" as:
```
dependencies {
add("ksp", projects.customKspPlugin)
}
```

### With this configurations after execution of gradle task ``kspWebMainKotlinMetadata`` are generated
- build/generated/ksp/metadata/commonMain
- build/generated/ksp/metadata/webMain

### There happened next problem:
``build/generated/ksp/metadata/webMain`` is combination of sourceSets commonMain and webMain.
I mean duplicity of commonMain.

## Expected behavior
Existence ``kspWebMainMetadata`` configuration.
Then configutaion of:
```
dependencies {
add("kspWebMainMetadata", projects.customKspPlugin)
}
```
will be generated only ``build/generated/ksp/metadata/webMain`` from only sourceSet of ``webMain``

### OR:
```
dependencies {
add("kspWebMain", projects.customKspPlugin)
}
```
will generate ``build/generated/ksp/webMain`` as combination of ``webMain`` + its parrents, in this case ``commonMain``
