fix release-prep script replacing dependencies versions in package.json #4679

Problem

When we prep a release, we run a script locally called release-prep.sh.

In it, there is a line that uses rg and sd to bump the version across the project (i.e. 4.0.0 -> 4.0.1).

Unfortunately, this means if there is a dependency with the same version we're bumping, it will bump that too 😅

Here is the exact line where we do this:
https://github.com/coder/code-server/blob/main/ci/build/release-prep.sh#L84

Example

Solution

It might be worth breaking this into two lines:

1. first rg -> sd replaces the first instance in package.json
2. ignores package.json but updates the other files (i.e. markdown)

To summarize, we should split the current functionality into two calls:

• update the package.json (only first string it finds)
• update the markdown files
