update deps incl. electron to v25, fix stylelint segmentation dump

[khassel]

• update electron to v25
• added overrides: section to package.json to fix Segmentation fault (core dumped) stylelint/stylelint#6898 (must be removed when fixed upstream, fixing the version to v15.6.2 did not fix the problem)
• update other deps
