Only try to match the pattern categories and get the label if the theme pattern uses the `categories` parameter. Otherwise there will be a TypeError when using the filter.

The array fallback is not needed inside getTermLabels, because getTermLabels is used as the value for defaultCategories, which is an empty array by default when it is used inside the function CreatePatternModalContents.

I briefly looked into adding a Playwright test for this but I was not able to figure out if there was a way to test a theme provided pattern. |

Oh, or I am supposed to get theme patterns by |
|
So I think the test should wait until TT5 is released, so that it can be added to the gutenberg-test-themes. |

For tests we're using the empty theme, where we can add stuff, like templates, patterns etc.. Did you try adding one there? |
|
I did not: I am torn about that because then it wont be empty 😅 |
I get it 😄 , but it's not entirely empty right now. Anyway.. This fix is a JS pretty strait forward one, and I believe it would be fine not to add a test. |

What Why & How
When a pattern is duplicated, there is a modal with an input field that contains the labels of the pattern categories:
the information about the category is passed on to the new pattern.
The function that gets the labels compares the category from the theme pattern with the existing registered pattern categories, to make sure that the category exists and is displayed with the correct label.
However, the code did not take into account that theme patterns can be registered without the optional
categoriesparameter.This PR makes a small change to the filter and mapping using optional chaining, to avoid a TypeError when the
categoriesparameter is not used.Closes #66888
Testing Instructions
Activate a theme that registers a pattern without the
categoriesparameter. This can be a classic theme or a block theme, for example Twenty Twenty-Five.Open the Patterns screen from Appearance > Patterns or from Appearance > Editor > Patterns.
Locate the pattern that does not have a category.
Select the option to duplicate the pattern.
Confirm that the modal with the information about the duplicated pattern opens and that there are no JavaScript errors in the browser console.
Click the button at the bottom of the modal to duplicate the pattern. Confirm that there are no issues related to the category of the new pattern.
Now, select a different pattern that has a single category or multiple categories, and duplicate it.
Confirm that the category labels show correctly in the modal and that there are no new issues/ regressions.
Click the button at the bottom of the modal to duplicate the pattern. Confirm that there are no issues related to the category of the new pattern.
