Update description of VSCode extensions

[gares]

The info was outdated. This is a minimal fix.

Looks good to me (and this is was somehow awaited information to take decisions on #218)

[herbelin]

BTW, does this mean that the VsCoq 1 vs VsCoq 2 difference of terminology disappears and that VsCoq 1 is just considered an old non-lsp variant of VsCoq?

I'll leave to the home pages of the projects to detail these things.
If we put too much info here it is going to be outdated too soon imo.

OK. It that I was afraid that the text "Both extensions are based on LSP" led to confusion if VsCoq 1 is still an option.

This is a much-needed fix, and since we didn't manage to converge on a description that would say more, I agree that it is reasonable to defer additional explanations to the projects' webpage.

Just a minor suggested change to clarify the situation for users who were already aware of the existence of VsCoq before.

If you are referring to #218, I should talk with Emilio but it may converge. This PR (#226) is however needed.

Done, I let you merge @Zimmi48 / @herbelin !
