Is your feature request related to a problem? Please describe.
Currently, all blocks from the Tour Operator Plugin appear in the block inserter by default. Most of these blocks are primarily used within the site editor in patterns or block templates, which clutters the block inserter unnecessarily.

Describe the solution you'd like
We propose setting the inserter property to false for all blocks in the Tour Operator Plugin, except for the Tour Collections block. This will hide these blocks from the inserter, ensuring that they are only accessible when used in patterns or templates within the site editor. The Tour Collections block will remain visible in the block inserter for easy access.

Describe alternatives you've considered
Alternatively, we could allow all blocks to remain visible in the inserter. However, this approach would overwhelm users with block options that are rarely used directly, detracting from the usability of the editor.

Additional context
Based on the WordPress documentation, setting inserter: false hides the block from all UI elements unless explicitly inserted programmatically, which fits our requirements perfectly.
