Fixing script to read ascii code

[gizas]

-- Bug

What does this PR do?

WHAT: Updates makefile to read from different value of version.doc file
WHY: The doc-branch is a field that no longer is udpated. Thus we replace it with stack-version field

Why is it important?

To avoid wrong references to main and alwasy reference to latest release of templates

This pull request does not have a backport label. Could you fix it @gizas? 🙏
To fixup this pull request, you need to add the backport labels for the needed
branches, such as:

• backport-v./d./d./d is the label to automatically backport to the 8./d branch. /d is the digit

NOTE: backport-skip has been added to this pull request.

@cmacknz I move our discussion here: #3523 (comment)

Only thing is that stack-version still seems not updated in main branch. See here: https://github.com/elastic/elastic-agent/blob/main/version/docs/version.asciidoc#L1

Is this expected?

It appears the :stack-version key here isn't being updated properly since this shouldn't be 8.8.

The one you want and is guarnateed to be right is

elastic-agent/version/version.go

Line 7 in 99b14c8

const defaultBeatVersion = "8.12.0"

There are a couple of examples for parsing this you could reuse. For one example see

elastic-agent/.buildkite/scripts/common.sh

Line 16 in 99b14c8

BEAT_VERSION=$(grep -oE '[0-9]+\.[0-9]+\.[0-9]+(\-[a-zA-Z]+[0-9]+)?' "${WORKSPACE}/version/version.go")

You'd still have to drop the patch version.

[cmacknz]

Ah I also now see why we were trying to use doc-branch because this needs to be main and not 8.12 for main.

I would suggest git branch --show-current but that will break when this is run on developer branches.

[gizas]

I changed it to read from version.go

Both managed and standalone updated

[cmacknz]

All of the files probably should have updated, not just one.

Do you have any idea why the check fails in https://fleet-ci.elastic.co/blue/organizations/jenkins/elastic-agent%2Felastic-agent-mbp/detail/PR-3556/4/pipeline ?
