Subject: [PATCH] languages: Check whether to update
 `typescript-language-server` (#44343)

Closes #43155

Adds a missing check to also update packages when the
`typescript-language-server` package is outdated.

I created a new `SERVER_PACKAGE_NAME ` constant so that the package name
isn't coupled to the language server name inside of Zed.

Release Notes:

- Fixed the typescript language server falling out of date
