x/website: blog v2 modules article contains confusing command output

[rillig]

https://go.dev/blog/v2-go-modules says:

$ mkdir v2
$ cp *.go v2/
building file list ... done
call_option.go
gax.go
header.go
invoke.go
tools.go

sent 10588 bytes  received 130 bytes  21436.00 bytes/sec
total size is 10208  speedup is 0.95
$

The command cp is not verbose by default, so it prints neither of these lines:

• building file list
• sent …
• total …

These lines should be removed.

Same article, next typo:

adding a v2/ suffix

The suffix is /v2, not v2/.
