gh-125766: Docs: minor rewording of installation on Linux section

[partev]

there are three changes in this pull request:

1. remove the word "easily" from "You can easily compile the latest version of Python from source." So it becomes "You can compile the latest version of Python from source." because that word is unnecessary.
2. remove the word "easily" from "... you can easily make packages for your own distro." so it becomes "... you can make packages for your own distro."
3. replace "In the event that Python doesn’t come preinstalled and isn’t in the repositories as well, you can easily make packages for your own distro." with "In the event that the latest version of Python doesn’t come preinstalled and isn’t in the repositories as well, you can make packages for your own distro." The reason is because almost all Linux distros have python in pre-installed or in their repos, so the main reason to compile python or make python packages is to get a more recent version that is not available in your distro's repositories.
