docs(devtools): make markdown consistent

[dborysov]

🎯 Changes

Currently there is a bug, which prevents proper rendering of the links if there are both MD & HTML syntax in the same line (see https://tanstack.com/query/latest/docs/framework/react/devtools), probably should be fixed in @tanstack/markdown. Not sure that the source code of this package is published?

In the meantime, I just converted all links to html.

Converting everything (logos) to markdown won't work because we need to set width/height, which can't be done in markdown

📝 Walkthrough

Walkthrough

Updated the framework devtools docs to show Chrome, Firefox, and Edge extension links with inline browser logo images instead of plain text links.

Changes

Browser devtools extension links

Layer / File(s)	Summary
Inline icon links docs/framework/angular/devtools.md, docs/framework/preact/devtools.md, docs/framework/react/devtools.md, docs/framework/solid/devtools.md, docs/framework/svelte/devtools.md, docs/framework/vue/devtools.md	Each framework devtools guide now renders the Chrome, Firefox, and Edge extension items as icon-prefixed links instead of plain text links.

Poem

🐰 I hopped through docs with a tiny grin,
Chrome, Firefox, and Edge now glow within.
Icons beside the links do peep and gleam,
A carrot-bright trail in each framework theme.
Hop-hop—devtools shine in a tidy dream.
