fix: Truncate Notion select options that exceed length limit

[dvanoni]

Fixes #240

Summary

Notion imposes a limit of 100 characters for the names of select and multi-select options. This presented an issue for the Collections property when collections with long-enough names were nested. Tags could also suffer from the same issue if a single tag had a name longer than 100 characters.

To resolve this, we now truncate option names in the middle of the string so that they conform to the 100-character limit.

Example

The following nested collections result in a name with 117 characters:

This name has 27 characters ▸ This name has 27 characters ▸ This name has 27 characters ▸ This name has 27 characters

This name is now truncated to the following:

This name has 27 characters ▸ This name has 27 cha…e has 27 characters ▸ This name has 27 characters
