docs/commands: add to.md, update subcommands (#1715)
This adds a top-level document for the new `to` command, with a list (of links) of all the subcommands.

All the to-* subcommands keep their filename, but the content is updated to use the new subcommand syntax.

Since not all subcommands have documentation, some items in the list are just text without a link. Also filled the list for the undocumented from* commands in the same style.

Fixes #1709

# from-csv
Converts content (string or binary) into a table. The source format is specified as a subcommand, like `from csv` or `from json`.
Use this when nushell cannot determine the input file extension.
## Available Subcommands
* from bson
* [from csv](from-csv.md)
* from eml
* [from ics](from-ics.md)
* from ini
* [from json](from-json.md)
* [from ods](from-ods.md)
* from sqlite
* from ssv
* [from toml](from-toml.md)
* [from tsv](from-tsv.md)
* from url
* [from vcf](from-vcf.md)
* [from xlsx](from-xlsx.md)
* from xml
* [from yaml](from-yaml.md)
*Subcommands without links are currently missing their documentation.*
## Example for `from csv`
Let's say we have the following file :
```shell
> cat pets.txt
animal, name, age
cat, Tom, 7
dog, Alfred, 10
chameleon, Linda, 1
```
`pets.txt` is actually a .csv file but it has the .txt extension, `open` is not able to convert it into a table :
```shell
> open pets.txt
animal, name, age
cat, Tom, 7
dog, Alfred, 10
chameleon, Linda, 1
```
To get a table from `pets.txt` we need to use the `from csv` command:
```shell
> open pets.txt | from csv

# │ animal │ name │ age
───┼───────────┼─────────┼──────
0 │ cat │ Tom │ 7
1 │ dog │ Alfred │ 10
2 │ chameleon │ Linda │ 1
━━━┷━━━━━━━━━━━┷━━━━━━━━━┷━━━━━━
```
