feat(astro): Add OrganizationProfile custom pages and links

[wobsoriano]

Description

This PR adds support for custom pages and links in the <OrganizationProfile /> Astro component. It implements the same behavior with the React counterpart:

In a dedicated page:

<OrganizationProfile>
    <!-- Custom page -->
    <OrganizationProfile.Page label="Terms" url="terms">
        <div slot="label-icon">Icon</div>
        <div>
            <h1>Custom Terms Page</h1>
            <p>This is the custom terms page</p>
        </div>
    </OrganizationProfile.Page>
    <!-- Custom link -->
    <OrganizationProfile.Link label="Homepage" url="/">
        <div slot="label-icon">Home</div>
    </OrganizationProfile.Link>
    <!-- Reorder default item -->
    <OrganizationProfile.Page label="members" />
</UserProfile>

Inside <OrganizationSwitcher /> component:

<OrganizationSwitcher>
    <OrganizationSwitcher.OrganizationProfilePage label="Terms" url="terms">
        <div slot="label-icon">Icon</div>
        <div>
            <h1>Custom Terms Page</h1>
            <p>This is the custom terms page</p>
        </div>
    </OrganizationSwitcher.OrganizationProfilePage>
    <OrganizationSwitcher.OrganizationProfileLink label="Homepage" url="/">
        <div slot="label-icon">Icon</div>
    </OrganizationSwitcher.OrganizationProfileLink>
    <OrganizationSwitcher.OrganizationProfilePage label="members" />
</OrganizationSwitcher>

Closes ECO-182
