Copying icons fails on second run if source directory is read-only

[K900]

Describe the bug
When the node_modules directory is read-only, the icon copying code will also copy the icon files as read-only, and fail to overwrite them on the next startup.

To Reproduce
Steps to reproduce the behavior:

1. chmod -R -w node_modules
2. Run n8n
3. Stop n8n
4. Run n8n

Expected behavior
n8n starts correctly.

Environment (please complete the following information):

• OS: [e.g. Ubuntu Linux 22.04] NixOS unstable
• n8n Version [e.g. 0.200.1] 0.208.1
• Node.js Version [e.g. 16.17.0] 16.18.1
• Database system [e.g. SQLite; n8n uses SQLite as default otherwise changed] SQLite
• Operation mode [e.g. own; operation modes are own, main and queue. Default is own] own

Additional context
The NixOS packaging model requires things to be read only, so we currently can't update n8n to the versions that added the icon copying code.

Hey @K900,

It looks like this should be resolved now, I am going to mark it as closed. If you are still seeing this issue let me know and we can look into it again.

Thanks, it is in fact resolved, I thought the PR would auto-close this.
