I also removed the making of the no longer needed data dir

+ DietPi-Software | Bitwarden_RS: Align indentation
+ DietPi-Software | Bitwarden_RS: Rename to "Bitwarden_RS" with underscore with matches the official spelling
+ DietPi-Software | Bitwarden_RS: Export HOME override and revert, to simplify it a bid and assure that it is set for all commands and sub commands where required
+ DietPi-Software | Bitwarden_RS: Add fallback URL for main download
+ DietPi-Software | Bitwarden_RS: Fix web vault install where G_CHECK_URL on the final archive fails, and move that to the install step

+ DietPi-Software | Align methods when downloading from GitHub archive via latest version tag

+ DietPi-Software | Bitwarden_RS: Web vault requires HTTPS to work with all browsers, so create a self-signed certificate.

+ DietPi-Software | Bitwarden_RS: Add SAN to self-signed TLS certificate, otherwise the official Bitwarden client refuses connection. As well this makes the connection appear "secure" in some browsers, at least after the certificate has been added to the trusted CA storage.

+ DietPi-Software | Bidwarden_RS: Assure 2 GiB memory and 1.5 GiB /tmp size for Rust install to /tmp and Bitwarden_RS build
+ DietPi-Software | Bidwarden_RS: Don't run multiple jobs concurrently, as one job can require > 500 MiB memory and can utilize all cores as well
+ DietPi-Software | Bidwarden_RS: Download and execute rustup as separate steps to allow separate error handling, even editing rustup-init.sh, when required, and avoid "eval" where we don't exactly know the scripts content.
+ DietPi-Software | Mycroft AI: Avoid running "dietpi-set_swapfile 1" if less than 100 MiB would be required, as such a small swap file size is now omitted by the script internally, which lead to ~50 MiB swap files on all 2 GiB physical RAM devices in the past.

+ DietPi-Software | Bitwarden: Allow using all CPU cores for cargo build when >= 3 GiB memory are available, else limit to 2 cores

+ DietPi-Software | Bitwarden_RS: If APT cache and/or archives have been moved to RAM, build can still run into OOM due to the large amount of DEB packages installed as dependencies. Be failsafe and clean both. As the binary cache file is removed, this could slow down further APT installs within the same run, but much less compared to limiting the build to a single thread and Bitwarden_RS is one of the last installs performed due to its location near the end of the install function.

+ DietPi-Software | Bitwarden_RS: Adjust listening port from 8000 to 8001 to avoid conflict with WebIOPi, IceCast and Koel
