v1.5.0 Features and polish

🎉 Introduces many new features and options!

See :h nvim-updater or the README for details.

Some highlights:

• Update notification system: Optionally generate notifications when new commits are available.
• Improved keymapping and <Plug>: Provides a more streamlined and easier approach to creating keymaps.
• short commit messages: show_new_commits() can now be displayed using short-format commit messages
• Lua function polish: All of the Lua functions can now accept parameters as a table in addition to the traditional syntax
• Terminal view polish: Floating terminals can now have a unique filetype and should properly enter/stay in insert mode.

Moving forward, development will be performed on a development branch matching its release version.
Updates will be pushed to main only when a release is completed.

This v1.5.0 release should be fairly stable.
