Add slot for Select Wallet button

[IlyaSemenov]

As a developer, I would like to customize <wallet-multi-button /> text (say change it from "Select Wallet" to "Connect Wallet").

Currently, it's practically impossible without overriding the whole 100-liner slot:

solana-wallets-vue/src/components/WalletMultiButton.vue

Lines 89 to 154 in f624f72

	<slot v-bind="{ ...modalScope, ...scope }">
	<button
	v-if="!wallet"
	class="swv-button swv-button-trigger"
	@click="modalScope.openModal"
	>
	Select Wallet
	</button>
	<wallet-connect-button
	v-else-if="!publicKeyBase58"
	></wallet-connect-button>
	<div v-else class="swv-dropdown">
	<slot name="dropdown-button" v-bind="{ ...modalScope, ...scope }">
	<button
	class="swv-button swv-button-trigger"
	:style="{ pointerEvents: dropdownOpened ? 'none' : 'auto' }"
	:aria-expanded="dropdownOpened"
	:title="publicKeyBase58"
	@click="openDropdown"
	>
	<wallet-icon :wallet="wallet"></wallet-icon>
	<p v-text="publicKeyTrimmed"></p>
	</button>
	</slot>
	<slot name="dropdown" v-bind="{ ...modalScope, ...scope }">
	<ul
	aria-label="dropdown-list"
	class="swv-dropdown-list"
	:class="{ 'swv-dropdown-list-active': dropdownOpened }"
	ref="dropdownPanel"
	role="menu"
	>
	<slot name="dropdown-list" v-bind="{ ...modalScope, ...scope }">
	<li
	v-if="canCopy"
	@click="copyAddress"
	class="swv-dropdown-list-item"
	role="menuitem"
	>
	{{ addressCopied ? "Copied" : "Copy address" }}
	</li>
	<li
	@click="
	modalScope.openModal();
	closeDropdown();
	"
	class="swv-dropdown-list-item"
	role="menuitem"
	>
	Change wallet
	</li>
	<li
	@click="
	disconnect();
	closeDropdown();
	"
	class="swv-dropdown-list-item"
	role="menuitem"
	>
	Disconnect
	</li>
	</slot>
	</ul>
	</slot>
	</div>
	</slot>

While some other buttons have fine-grain slots such as <slot name="dropdown-button">, there is no slot for the primary button.

@lorisleiva Is this possible to implement?
Seems like a minimal change. I'd like to be able to style it (like add tailwind w-full class to the button when in my sub menu)
