add vuejwtapp and vueoauth2app at the matrix in github-actions.yml

Fix #897 (roadmap at description)

[renanfranca]

@pascalgrimaud, @murdos: I removed vueapp and created vuejwtapp and vueoauth2app because the modules vue-jwt and vue-oauth2-keycloak have files with the same names, and both couldn't be applied in the same app in generate.sh.

[murdos]

Looks fine!
@pascalgrimaud : do you have some reluctance to add more generated apps in ci?

[pascalgrimaud]

@murdos : no, we can add new CI for testing new modules. If I remember well, there should be a check with md5sum or something like that. If the md5sum doesn't change, this job will stop, so in the end, we won't lost lot of time
