feat: set process.title to uptime-kuma

[Hill-98]

Summary

In this pull request, the following changes are made:

The process.title property sets the name of the current Node process as it appears in tools like ps/htop, which can help us better recognize the process.

process.title has length limit on Linux and macOS platforms, and can be set to a maximum of the length of the executable filename + arguments. uptime-kuma runs on node server/server.js, which we can set to maximum of 20 chars.
