DOC: Fix some docstring validation errors #59698
Part of an effort to close #59698

Added missing "See Also" section to the following methods:
```python
pandas.TimedeltaIndex.components
pandas.TimedeltaIndex.microseconds
```
and updated undocumented parameters for the following method:
```python
pandas.Timedelta.to_numpy
```
Removed the following strings from `code_checks.sh`:
```python
 -i "pandas.Timedelta.to_numpy PR01" \ 
 -i "pandas.TimedeltaIndex.components SA01" \ 
 -i "pandas.TimedeltaIndex.microseconds SA01" \
```

Thanks @amanlai  @amanlai - just as a note, if you have "close" on the same line as an issue number, GitHub will automatically close the issue when your PR is merged. Best to just have something like "Part of #XXXXXX".
