[Migration tooling] Tables

[bmorelli25]

Conversion

Tables are rendered as:

```{table}
:width: auto
| <header> | <header> | <header> | ... |
| -------- | -------- | -------- | ... |
|  <text>  |  <text>  |  <text>  | ... |
|  <text>  |  <text>  |  <text>  | ... |
|  <text>  |  <text>  |  <text>  | ... |
|   ...    |   ...    |   ...    | ... |
```

We support this table syntax but also just the regular GitHub flavored style which would be a bit cleaner in this case?

e.g just:

| <header> | <header> | <header> | ... |
| -------- | -------- | -------- | ... |
|  <text>  |  <text>  |  <text>  | ... |
|  <text>  |  <text>  |  <text>  | ... |
|  <text>  |  <text>  |  <text>  | ... |
|   ...    |   ...    |   ...    | ... |

They would render better on Github too.

Sidenote: I personally dread creating tables in markdown even when my editor helps me so i'd still like a specialized syntax for this e.g

```{code-table} <path to yaml_json>
:columns: prop1, prop3, prop4
```

and maybe revisit #17

Added your table suggestion to #160. I'm going to keep this issue open for now as there are likely some edge cases with tables that we won't see until the bug bash.
