[v3] Using the `task common:update:build-assets` command will overwrite Info.plist instead of merging it.

[rxliuli]

Description

When building the mac version of the app, I noticed that after manually modifying Info.plist and then re-running task common:update:build-assets, it overwrites all previous modifications. Check the code.

wails/v2/pkg/commands/build/packager.go

Line 131 in ca594c5

return os.WriteFile(targetFile, content, 0o644)

For example, when publishing to the AppStore, LSApplicationCategoryType must be included, but this key gets deleted every time I update the version, and I need to manually restore it, which is troublesome.

To Reproduce

wails/v2/pkg/commands/build/packager.go

Line 131 in ca594c5

return os.WriteFile(targetFile, content, 0o644)

Expected behaviour

Modify the processPList implementation to support merge operations for preserving custom modifications.

Thanks for opening 🙏 You've quoted v2 code though?

I couldn't find the code related to v3. Perhaps you could tell me where exactly the code that updates info.plist is located? That way I can create a PR to fix it.
