Documentation Pgx section update

[msavic-dev22]

The code example in Pgx section is outdated. Currently there is this code:

config, err := pgx.ParseConfig("postgres://postgres:@localhost:5432/test?sslmode=disable")
if err != nil {
    panic(err)
}
config.PreferSimpleProtocol = true

but PreferSimpleProtocol does not exists. Instead it should be:

config, err := pgx.ParseConfig("postgres://postgres:@localhost:5432/test?sslmode=disable")
if err != nil {
    panic(err)
}
config.DefaultQueryExecMode = pgx.QueryExecModeSimpleProtocol

@vmihailenco It looks like the link to contribute to the docs is broken. There is no way for us to make PR to update documentation

Thanks, the documentation will be updated on the next deploy.
