This is a small update to the installation instructions for some of the frameworks to make the instructions on editing the tsconfig file consistant across the frameworks, and remove some potentially confusing wording (if people read too fast...like me).
Mainly applying the gatsby tsconfig instructions to vite and astro, as it is the most clear.
Additionally changed the wording from:
```
Add the code below to the compilerOptions...
```
to:
```
Add the following code to the compilerOptions...
```
to avoid people easily misreading it as "add the code **below the** compilerOptions".
