Add tags to metadata

[juliasilge]

Related to rstudio/pins-r#570

Let's add the new tags option to the metadata in Python:

library(pins)
b <- board_rsconnect()
#> Connecting to RSC 2022.11.0 at <https://colorado.rstudio.com/rsc>
b %>% pin_meta("julia.silge/great-numbers")
#> List of 12
#>  $ file       : chr "great-numbers.rds"
#>  $ file_size  : 'fs_bytes' int 61
#>  $ pin_hash   : chr "4d1eb93dc2188114"
#>  $ type       : chr "rds"
#>  $ title      : chr "julia.silge/great-numbers: a pinned integer vector"
#>  $ description: NULL
#>  $ tags       : chr [1:2] "i-love-integers" "numbers-are-fun"
#>  $ created    : POSIXct[1:1], format: "2022-11-21 14:09:27"
#>  $ api_version: num 1
#>  $ user       : list()
#>  $ name       : chr "julia.silge/great-numbers"
#>  $ local      :List of 4
#>   ..$ dir       : 'fs_path' chr "~/Library/Caches/pins/rsc-e62371cfd77db754024f9c5ed3556a73/cc8ef31c-d6b3-4e0a-be8e-7992efffaee0/66084"
#>   ..$ url       : chr "https://colorado.posit.co/rsc/content/cc8ef31c-d6b3-4e0a-be8e-7992efffaee0/_rev66084/"

Once we have this implemented in R and Python, we can set tags = "vetiver" when we pin a vetiver model.

Any pin saved with tags in the metadata is currently unreadable in pins-python 😭. I'll add tags to the metadata today... (sorry, not sure how I missed this in the PR)

maybe time in the near future to circle back to adding compatibility tests to the R ci (rstudio/pins-r#610)

• the R and python scripts for the compatibility tests
• CI job

pins with a tags field should at least be readable now in v0.7.3

@juliasilge WDYT of us having R pins add tags metadata as either null or a list of strings? Currently, if you pin_write(..., tags="some_tag") it saves it as a string, rather than a list of strings.

AFAIK the result will be the same when reading meta into R (NULL or a vector of strings), so this is purely for convenience on the python side :) (which would be None, str, or list[str] right now)
