Add environment variable support to EditableTables

[Mosnar]

In the spirit of #10111 - it would be great if we could use the autosuggested environment variables and aliases within an editable table field. There's already a "template" column type, so it should be a small change. My use-case is that I have a plugin that connects to an external API that can have multiple nodes for redundancy, and ideally a user should be able to use environment variables here.

Just added this for the next release (bf8b0a6).

There’s a new autosuggest column type which supports setting suggestEnvVars and suggestAliases keys to true on the column definition:

{{ forms.ediatbleTableField({
    staticRows: true,
    cols: {
        secretKey: {
             type: 'autosuggest',
             heading: 'Secret key'|t('plugin-handle'),
             suggestEnvVars: true,
        },
    },
}) }}

Also added support for suggestEnvVars + suggestAliases to the template column type.

Note that for both of these column types, autosuggestions will only work for rows that were included on the initial page load. So best reserved for editable tables where staticRows is set to true.

3.7.24 is out now with that change.
