Update README clarify build from command line (JuliaLang#46290)

I fixed a few minor ambiguities in README: 1. Added a separate instruction to change into julia directory. It was conflated with checkout of latest release, but clearer to separate the two, since everyone needs to be in that directory regardless of whether they did a checkout. 2. Changed "from your Julia directory" to "change into the resulting julia directory" to make it clearer what directory is referred to. Changed upper- to lower-case to be consistent with subsequent references in README. 3. Rewrote instruction for `make` so that it assumes/clarifies user should already be in julia directory. 4. Same for `./julia` because user should already be in directory. 5. Removed "source" from "the julia source directory" because `make testall` should be executed from the same julia directory, and should not be confused with `src`. I have followed my updated instructions and verified that they work for myself.
