Scrib Desktop: äldre versioner att ladda ner

Printing arrives, and a bug that could replace a table cell's text with the whole note is fixed. That bug affected 1.10.2 and earlier, so updating is recommended. The .scrb format is unchanged.
- Table fix: after typing in a table cell, clicking the note and pressing Ctrl+End could replace the cell's text with the entire note, and the next save kept it. Clicking the note now takes the cursor out of the cell first. The first click on a new table now goes into the cell, and Tab in a cell no longer inserts a tab into the note.
- Printing: File > Print (Ctrl+P) prints the active note through the standard Windows print dialog, so any printer Windows knows about works, including Microsoft Print to PDF and Universal Print. Tables and SVG images do not print yet. Printing an encrypted note asks first, because the printout is not encrypted.
- Built with Flutter 3.47.7. Open, Save As and Insert Image now use Flutter's own Windows file dialogs.
Test suite grown from 670 to 707.

A rich-text note saved as .rtf now keeps its images. The file still opens in Word and WordPad. The .scrb format is unchanged.
RTF images:
- PNG and JPEG images are stored as they are. GIF, WebP and BMP images are converted to PNG. The width set in the editor and any image link are saved too.
- Opening an .rtf brings back its PNG and JPEG pictures, including ones saved by Word.
- Tables and SVG images still cannot be stored in RTF. Scrib asks before a save would remove them. Save as .scrb to keep them.
Also includes the 1.10.1 fixes:
- Closing Scrib no longer crashes.
- Rich text now saves under any file name, even one typed without an extension.
Test suite grown from 643 to 670.
