gdcdata prints extraneous manifest console output

[hermidalc]

In GenomicDataCommons 1.10 when you ran gdcdata you would get no extraneous console output. But since 1.12 and newer versions when you run gdcdata you get e.g.:

## Rows: 521 Columns: 5

## ── Column specification ────────────────────────────────────────────────────────
## Delimiter: "\t"
## chr (4): id, filename, md5, state
## dbl (1): size

## 
## Use `spec()` to retrieve the full column specification for this data.
## Specify the column types or set `show_col_types = FALSE` to quiet this message.

Which shouldn't be output to the console as users are not running manifest here, they are getting data so it should only show progress or be completely quiet depending on progress param setting.
