Updates Helm chart weight documentation

TL;DR
-----

Enhances the Helm chart weight documentation to provide better context
about how weight values affect installation order across different
Replicated deployment methods.

Details
--------

This documentation update clarifies the full impact of the `weight`
parameter in Helm charts across the Replicated ecosystem. Previously,
the documentation only explained how weight affects KOTS application
order, but didn't mention its relevance to the Enterprise Portal's
display of installation instructions.

The improved documentation now explicitly states that the weight
parameter is used not just by KOTS but also by the Replicated Enterprise
Portal to order charts in installation and update instructions. This
gives users a more complete understanding of how the weight parameter
influences both the technical installation sequence and the display of
information in the UI.

+The Replicated Enterprise Portal uses these weights to order the list of charts in the install and update instuctions they provide. See [View Install and Update Instructions](https://docs.replicated.com/vendor/enterprise-portal-use#view-install-and-update-instructions). When installing with KOTS or the Embedded Cluster, `weight` determines the order in which KOTS applies the Helm chart. 
 
 In KOTS v1.99.0 and later, `weight` also determines the order in which charts are uninstalled. Charts are uninstalled by weight in descending order, with higher weights uninstalled first. For more information about uninstalling applications, see [remove](kots-cli-remove) in _KOTS CLI_.
