Fixes #5282 by @obulat

Description

This pull request fixes the issue where scrollbars were displayed unnecessarily in Windows browsers due to the use of overflow-y-scroll in default.vue and VModalContent.vue.

Testing Instructions

1. Run the application on a Windows machine locally.
2. Go to the homepage.
3. Verify that scrollbars are only visible when the content exceeds the viewport size and remain hidden if the content fits perfectly within the viewport.

Hi, @Anuj012004, thank you for your PR! Could you update the PR description? Something like #5286 would be great.

[Anuj012004]

Hi @obulat, I have updated the description. Is it okay now?

[Anuj012004]

Hi [@obulat, @dhruvkb],

I accidentally cleared the original description in my PR (#5285) and replaced it with my own. Could you please confirm if it's okay or if I need to change it? Also, is there any way to recover the original description?

Hey @Anuj012004, the PR template should be populated by filling out the [placeholder] parts and checking off the task list [ ] → [x]. I'ved restored the original template that you can now properly fill out.
