Could you add an option to turn off the automatic update of the frontmatter

### 🐛 Describe the bug

Currently, the automatic update of the frontmatter is breaking the link format by converting them to tag format. Could you add an option to turn off this feature?

### Config

```lua
local user = "phuongpd"

Start from the configured note_frontmatter_func entry point and trace where obsidian.nvim automatically updates frontmatter and converts links to tags. Reproduce the reported conversion, then verify that a new configuration option disables the automatic update while preserving the link format.
