[FR]: Add -Installer and -portable to release asset filenames + remember and reuse the installer type from last time

Brief description of the feature request

Add -Installer and -portable to release asset filenames + remember and reuse the installer type from last time.

Detailed description of the feature request

My first suggestion is to insert -Installer and -portable to the Release asset filenames (moving the architecture part to the end) to make them more distinguishable, for example:

	___-win10.exe	___-win10.7z
Current	rssguard-4.8.0-e24f4575a-win10.exe	rssguard-4.8.0-e24f4575a-win10.7z
New	rssguard-4.8.0-e24f4575a-Installer-win10.exe	rssguard-4.8.0-e24f4575a-portable-win10.7z

I have in mind e.g. the Notepad++ and Subtitle Edit repos:

https://github.com/notepad-plus-plus/notepad-plus-plus/releases
https://github.com/SubtitleEdit/subtitleedit/releases

---

My second suggestion is to remember and reuse the installer type from the last time, so that the upgrade procedure can continue without the user having to select the file (out of 8 possible for windows in my case). This is for two reasons:

• first, it would make the procedure simpler by omitting the need to select the file.
• Second, e.g. I have the regular version installed on win11. I never want to switch to the lite version (or the win7) during upgrades. So, if I have used the non-lite ___-win10.exe file last time I installed/upgraded, If I (simply) choose "Download" in the next "Check for updates" prompt, then it will directly download the new non-lite ___-win10.exe without me asking, and then just continue with the upgrade (the UAC prompt and so on).
