`PollingFileWatcher` Issue while running `dotnet watch run` with wsl volume mounts

### Describe the bug
A clear and concise description of what the bug is.

- Windows Version: Windows 10 with WSL2 integration
- Docker Desktop Version: 2.4.0.0 (48506) stable
- Not running inside a virtualized Windows e.g. on a cloud server or on a mac VM

I have a dotnet core project which is stored in c drive of my windows system.
I have wsl2 integration with my docker desktop.

I am trying to run my application in docker using `dotnet watch run` and wanted to reflect the changes I do in `MySampleService` in docker build.

When I do `docker-compose up`

I am getting following error in docker logs:


### Expected behavior
`dotnet watch run` executes without any issues and track the file changes done in `MySampleService` folder

### Actual behavior
`PollingFileWatcher` issue is occurring sometimes

### To Reproduce

I have following folder structure:
* Some Folder in C drive
* MySampleService
* bin
* obj
* some-code.cs
* docker-compose.yml

Following is my docker-compose.yml
```
version: "2.1"
services:
my-sample-service:
image: mcr.microsoft.com/dotnet/core/sdk:3.1-alpine
working_dir: /usr/src/app/MySampleService
volumes:
- ./MySampleService:/usr/src/app/MySampleService
environment:
"DOTNET_USE_POLLING_FILE_WATCHER": 1
entrypoint: "dotnet watch run --urls=http://0.0.0.0:5010"

- The IDE (VS / VS Code/ VS4Mac) you're running on, and it's version: using command prompt to build and run

Can somebody help me in fixing this issue? 🙂
