Did anyone produce updates on existing published papers later on?
Or is it always that when it's submitted, then "that's the way it is"?

Actual updates are unlikely. Subsequent work is frequent and valued. The problem is that an "update" assuming content is changed and not just form, could make citations made in the interim invalid.
Some publishers will publish notes or errata on papers found to be flawed.
Books get "corrected" editions published, but it isn't a general practice for papers. Even for online publication, changing the text makes some subsequent work (quoting) obsolete. It requires work that leads to as many problems as it solves, even for typos.
Note, however, that the paper published is almost never the same as the paper submitted. It goes through a review and editing process that can result in quite a lot of changes. But once published it is pretty much cast.
While @Buffy's answer holds true in most cases, it is worth noting that a number of disciplines have a system of two-stage publications that are explicitly designed around publication of an updated version.
For example, in many computer science fields, papers accepted in a conference are encouraged to later send an extended version to a journal. Both enter the scientific record, and the journal version is intended to be a more authoritative and final version, citing and superseding the original, and typically with at least 30% more material than was in the original.
I have seen this beginning to appear in some other fields as well, e.g., with extended abstracts in a conference being invited to publish a full paper in a journal.
In large areas of physics and mathematics, we are reading papers on arXiv and paying little attention to their published versions. (Assuming there is a published version, which is not always the case.) When there is a correction or improvement to be made post-publication, it is often done on arXiv only, as this is much easier than sending an erratum to the journal, which nobody would notice anyway.
Example: an arXiv preprint and the published version. In this case the title and format differ. And the preprint has corrections post-publication.
Example: this article has 9 versions on arXiv including 4 prior to publication in a journal, and 5 after publication. Between the first version post-publication (v5) and the last version (v9), 4 years have passed, and the article has grown from 36 to 55 pages.
There's a journal series that does exactly this - the Living Reviews series published by Springer. An example is Living Reviews in Relativity. From their description:
Living Reviews is unique in maintaining a suite of high-quality reviews, which are kept up-to-date by the authors. This is the meaning of the word "living" in the journal's title.
So one can expect articles published in Living Reviews in Relativity to be up-to-date. Most other papers, however, will not have been updated and so can be old or even completely superseded by later data.
