Fix icon tooltip alignment on instructions modal

This commit fixes a UI misalignment issue for toolips in the download
instructions modal.

The existing margin on icons caused tooltips to be misaligned upon hover
or touch.

Changes include:

- Introduce wrapper elements to encapsulate the margin, ensuring
  tooltips align with the corresponding icons.
- Extract the information incon into a separate Vue component to adhere
  to the single-responsibility principle and improve maintainability.
- Remove redundant newline at the end of 'Open terminal' tooltip to
  reduce the visual clutter.
