Reproduction steps:
1. Create a new project
2. In the "Manifest.json" add these two lines at the bottom of the dependencies list
"com.unity.localization": "0.10.0-preview",
"com.unity.platforms": "0.10.0-preview.10"
3. Observe the Console

Expected result: no Package errors in the Console
Actual result: multiple Package errors are outputted in the Console

"GUID [5e831756de21ed644b1ee7c64af6a831] for asset 'Packages/com.unity.platforms/Editor/Unity.Build/ObjectPool/CollectionPool.cs' conflicts with:
'Packages/com.unity.localization/Runtime/Utilities/ObjectPool/CollectionPool.cs' (current owner)
We can't assign a new GUID because the asset is in an immutable folder. The asset will be ignored."

Reproducible with: Localization 0.10.0-preview, Platforms 0.10.0-preview.10 (2020.2.3f1, 2021.1.0b4, 2021.2.0a3)
Not reproducible with: Localization 0.10.0-preview, Platforms 0.4.0-preview.5 (2019.4.19f1), Platforms 0.9.0-preview.9 (2020.2.3f1, 2021.1.0b4, 2021.2.0a3)
Couldn't test with: 2018.4.30f1 (no platforms package)

Notes:
- If the Platforms package version is lower than 0.10.0 preview.10, the errors do not reproduce
