fix: Formatting issue in the installation page of Integration testing

[AryanCruise]

What has changed?

This PR corrects the Markdown formatting in the installation guide (installation_tabs.md), specifically within the Linux, macOS, and Windows sections.

This resolves a rendering bug where bash code blocks were not properly indented inside their numbered list items. This lack of indentation caused the Markdown parser to break the list's structure, leading to visual alignment issues. The fix ensures all lists containing code blocks now render correctly with consistent styling.

Also fixed the title names above code blocks in the Linux native section, which didn't have the same text formatting as other sections.
