fix: change session start log level

[element-code]

Description
The session class clutters out-of-the-box configured logs with debug information about its driver initialization on startup, using a INFO classification.
This is especially problematic in authenticated webapps as every request will write at least one info message.
The message itself has a debug purpose and therefore should be classified as DEBUG

I agree, that using info may pollute the logs unnecessarily. I wouldn’t be against treating this as a bug.

Still, we will need a changelog entry.

Side note... Items on the issue description checklist should only be marked if they are accurate - thanks!

I don't think this is a bug, but I would not be against to change to DEBUG.
I think it is better that this PR goes to 4.6 branch.

Which file I need to edit for the changelog entry @michalsn?
I think this could be treated as a bug, since it only relates to application debugging and shouldn't be breaking in any production environment, therefore.

@element-code This one: https://github.com/codeigniter4/CodeIgniter4/blob/develop/user_guide_src/source/changelogs/v4.5.6.rst

[michalsn]

Thank you.

In general, we don't enter the PR number in the changelog.

[element-code]

Alright, should I squash or do you squash to merge?

[michalsn]

We can squash on merge - we just have to wait for one more approval.

This is a great improvement, it was always bothering me!🤓

[michalsn]

@element-code Thank you!

This was a very frustrating situation for me, so I'm glad it got resolved. Also, are there no new features or updates being made to CI4? Has its development been stopped

@mbnl What do you mean?

The latest release was a month ago: https://github.com/codeigniter4/CodeIgniter4/releases/tag/v4.5.5

The new features go to the 4.6 branch: https://github.com/codeigniter4/CodeIgniter4/tree/4.6, which is ahead of the develop by more than 300 commits.
