Enable alternative OKTETO_INSTALLATION_PATH for install/upgrade script

[viddo]

Is your feature request related to a problem? Please describe. I'd like to install multiple versions of okteto and be able to choose where the binary is written. Primary use-case is for confirming bug before writing up a report, specifically to ease comparing behavior between a stable / beta version.

Describe the solution you'd like

Hypothetical, proposed happy-path:

curl https://get.okteto.com -sSfL | OKTETO_CHANNEL=beta OKTETO_INSTALLATION_PATH=/tmp/okteto-beta sh
> Using Release Channel: beta
> Using Version: 2.20.0-beta.1
> Using custom installation path: /tmp/okteto-beta
> Downloading https://downloads.okteto.com/cli/beta/2.20.0-beta.1/okteto-Darwin-arm64

Describe alternatives you've considered

I'm aware that I can manually download a release from Github's release page, e.g. https://github.com/okteto/okteto/releases/tag/2.20.0-beta.1 but I find it clunky when there already exist a script

Additional context

• I believe it should suffice to modify scripts/get-okteto.sh?
• Suggested behavior:
  • OKTETO_INSTALLATION_PATH is optional
  • OKTETO_INSTALLATION_PATH requires a full path to binary if it's defined. E.g. /tmp would not be accepted and fail early
  • Set path is created if it does not exist, and fail early indicating what is wrong, e.g. lacking permission to create directory, …

When triaging/working on this, be aware of the implications of this and the dynamic Kubetoken feature. If the CLI is not installed in the PATH, it won't be used for the Kubeconfig generated by Okteto.

FWIW, found workaround in case someone is interested in this for whatever reason, it's enough to make a shell script to get a hold of older versions by steps outlined in release → installation methods https://github.com/okteto/okteto/blob/eab2d4914fc3628455639bed71a0182cc8438477/docs/RELEASE.md?plain=1#L43-L62
