Expand on mention of "Develop" branch in Handbook Codebase section

[magaliechetrit]

Go to [WordPress Contributor Handbook Codebase Section](
​https://make.wordpress.org/core/handbook/contribute/codebase/) then [How Code In WordPress Is Organized](​https://make.wordpress.org/core/handbook/contribute/codebase/#how-code-in-wordpress-is-organized)

There is a mention of "If you are using the “develop” repository, as mentioned above". This is a little confusing because some development sequences use "develop" as a branch. Furthermore, there is more than one type of repo mentioned, so I'd like to suggest an edit to expand or clarify.

"If you are using any of the "develop" repository mentioned above, ..."

If you are using either of the Git or Subversion repositories mentioned above
