Removing tss-react dependency

[garronej]

Hello,

I was reviewing your setup, good job!

Since you've opted for using @emotion as your styling solution I figured that it dosen't make much sens to have tss-react as well.

I also removed @emotion/server since it isn't nessesary in Next App Router setups.

One more thing I noted is that you're hardcoding the dsfr color values and that you're using colors options instead of the colors decision.
Are you aware of this tool?

https://components.react-dsfr.codegouv.studio/?path=/docs/%F0%9F%8E%A8-color-helper--page

You can replace:

<Typography
  variant="h5"
  style={{ 
    color: "var(--blue-france-sun-113-625)", 
    marginBottom: fr.spacing("3v") 
  }}
>

</Typography>

by:

<Typography
  variant="h5"
  style={{ 
    color: fr.colors.decisions.background.flat.blueFrance.default, 
    marginBottom: fr.spacing("3v") 
  }}
>

</Typography>

This way you're getting type safety.
