Description

I am trying to use Nextra for a project where the content (.md files) lives inside a git submodule. When I build I get a lot (~1.5k) of the following warning.

warn [nextra] Failed to get the last modified timestamp from Git for the file [...]

I would be fine just disabling timestamps in my project (for the time being) but I can't work out how to do that either.

To Reproduce Try building https://github.com/jajaperson/next-notes/tree/a5f5970a60959919b65539e42ebcfecbeb9153a9

Research direction
Investigate how Nextra retrieves git timestamps for files, particularly for files in submodules. Look for configuration options to disable timestamping or handle submodule repos. Check the Nextra source code in the `nextra` package for the warning message. Consider suggesting a fallback or a way to opt out of timestamping.
