Regression: post excerpt block's excerptLength attribute is ignored, excerpt length is always limited to 55.

Description

The Post Excerpt block is intended to display up first 100 words of an excerpt, as mentioned when first introduced - #44964 (comment)

However, some time since then,

gutenberg/packages/block-library/src/post-excerpt/block.json

Line 22 in 24fad40

"default": 55

The excerpt block will only display, at most, the first 55 words of a post (the default value of the excerptlength attribute), even if you just adjust the excerpt block's attributes to more than 55.

The excerptLength attribute will correctly display the number of words on the front end if the ExcerptLength attribute value is below 55.

Step-by-step reproduction instructions

1. create and publish a few posts of post type post that contain more than 100 words in each post; do NOT set a custom excerpt.
2. create a new page
3. insert new query block
4. include the excerpt in the post template and set the excerpt's attribute to a value above 55. I have a test case here, which assigns the value to 75
5. publish page

What happens:
the excerpts that displays on the published page are 55 words. You'll see in the video that this issue occurs within the editor and on the front end.

Note, there is an open pull request to fix this, #61888

Good catch, @skorasaurus!

I think excerpt length logic also needs an update after - https://core.trac.wordpress.org/changeset/58065.

@swissspidy, do you know if anyone created a follow-up PR in Gutenberg?

Nope, the issue is still open, see #53570

I suggest closing this one as a duplicate.
