Add command to upgrade tests to comply with profile 24.2 validation

[davelopez]

Closes #277

This pull request adds a new command (by default, the keybinding is ctrl+alt+u) to update test cases to the new validation requirement for tool tests introduced in Galaxy 24.2 and planemo.

A bit of context

Suppose we have a tool whose inputs section looks as follows:

<inputs>
    <conditional name="c1">
        <param name="c1_action" type="select">
            <option value="a1" selected="True">A 1</option>
            <option value="a2">A 2</option>
        </param>
        <when value="a1">
            <param name="c1_a1_p1" type="text"/>
            <repeat name="rep1" title="Sample repeat">
                <param name="rep1_p1" type="text"/>
            </repeat>
        </when>
        <when value="a2">
            <param name="c1_a2_p1" type="text"/>
            <section name="int" title="Integer Section" expanded="true">
                <param name="int_test" value="1" type="integer"/>
            </section>
        </when>
    </conditional>
</inputs>

And then we have a test in out tests section declaring params in the following way:

<test>
    <param name="c1_action" value="a1"/>
    <param name="c1_a1_p1" value="A 1"/>
    <param name="rep1_p1" value="r"/>
    <output name="out1">
        <assert_contents>
            <has_text text="a1"/>
        </assert_contents>
    </output>
</test>

In this case, the tool linting will complain with the following warnings:

Test 1: failed to validate test parameters against inputs - tests won't run on a modern Galaxy tool profile version. Validation errors are [Invalid parameter name found c1_action]

How it works

You can now run the extension command using the default key shortcut ctrl+alt+u, or search for it in the command palette as shown in the following video:

UpdateToolTests.mp4

The command will try to rewrite the params in the test cases to comply with the 24.2 validation profile.
