Avoid name duplication of the enso universal launcher

[JaroslavTulach]

There are two executables named enso among the daily bits we produce. That's confusing and we shall fix it.

One of them is called Enso launcher. To learn about it, please visit our download page: https://github.com/enso-org/enso/releases/tag/2024.1.1 - the download is in section called Enso Engine on that page, but in fact, it is not the engine, it is the launcher!

To learn more abou tthe enso launcher visit this documentation page - it contains nice description of the whole universtal launcher/updater picture...

However to benefit from the work done by

• Support for --jvm option in Enso runner #10374
• and to fulfill the vision as discussed in Launching Enso programs instantly #10121

we need to find a better location for exposing native image built launcher. The idea is to rename the launcher to ensoup:

It is a nice, illustrative name derived from the rustup example that nicely describes one of the purposes of ensoup - download the distributions of Enso automatically. Once the enso in the bundle is renamed to ensoup, we can proceed with placing a native image built binary next to it under the name enso - but that's for a different PR.

I've just downloaded the latest nightly and it contains the ensoup executable:

tar ftvz enso-bundle-2024.3.1-nightly.2024.7.17-linux-amd64.tar.gz  | grep enso/bin
drwxr-xr-x ci/ci             0 2024-07-17 04:29 enso/bin/
-rwxr--r-- ci/ci      58969568 2024-07-17 04:29 enso/bin/ensoup

the executable seems to work to some extend. I can ensoup new path_to_a_project and it runs. I haven't tested the other functionality (CCing @radeusgd), but in general things seem to work.

I have downloaded the Windows bundle.

Seems to work OK to me. I've checked most of the functionality, incl. the installation feature and all seem to work as expected. I have only not checked the self-upgrade.

I will be starting using ensoup from now on :) 🥣
