Revert "CI: Pin blosc to fix pytables"
Reverts pandas-dev/pandas#58209
Thanks @lithomas1  Owee, I'm MrMeeseeks, Look at me.

There seem to be a conflict, please backport manually. Here are approximate instructions:

1. Checkout backport branch and update it.

```
git checkout 2.2.x
git pull
```

2. Cherry pick the first parent branch of the this PR on top of the older branch:
```
git cherry-pick -x -m1 8b6a82f35a9dd8437564b50631b86b6a7e8c0251
```

3. You will likely have some merge/cherry-pick conflict here, fix them and commit:

```
git commit -am 'Backport PR #58218: Revert "CI: Pin blosc to fix pytables"'
```

4. Push to a named branch:

```
git push YOURFORK 2.2.x:auto-backport-of-pr-58218-on-2.2.x
```

5. Create a PR against branch 2.2.x, I would have named this PR:

> "Backport PR #58218 on branch 2.2.x (Revert "CI: Pin blosc to fix pytables")"

And apply the correct labels and milestones.

Congratulations — you did some good work! Hopefully your backport PR will be tested by the continuous integration and merged soon!

Remember to remove the `Still Needs Manual Backport` label once the PR gets merged.

If these instructions are inaccurate, feel free to [suggest an improvement](https://github.com/MeeseeksBox/MeeseeksDev).
                 @lithomas1 was https://github.com/pandas-dev/pandas/pull/58209 ever backported? We can remove the needs backport label here?

and change the milestones? This wasn't needed for 2.2.3. 

Thanks for checking. I think this is causing problems for 2.2.x now, backporting.
