Access error while reading project files.

[sheridanchris]

Describe the bug
When crawling through project files in a solution, encountering a directory which proj-info doesn't have permission to read, will result in a System.IO.Exception: Permission Denied

To Reproduce
Steps to reproduce the behaviour:

1. Create an F# project
2. Add a folder/files that requires elevated permissions (root/admin)
3. Try loading the solution with Ionide
4. Look at F# log output with the adaptive lsp server enabled (without this, the error will still occur but the exception doesn't appear in the output).
5. See error

Expected behaviour
I expected the directory to be ignored.

Environment (please complete the following information):

• OS: Windows + Linux (Arch Linux)
• Ionide version: 7.3.0 (latest)
• VSCode version: 1.72.2-1 (latest)
• dotnet SDK version: 6.0.402
• mono / .Net Framework version: N/A

Additional context
I'm using docker-compose to create volumes for PostgreSQL + Redis. On Linux and Windows, these volumes require elevated (admin/root) privileges to access.

I would like to create a PR to fix this issue.
