fix: Refactor parameter names and update documentation

[Dor-bl]

Refactored parameter names across multiple interfaces for clarity:

• IPushesFiles.PushFile: base64Data to stringData and file
• IFindsByFluentSelector.FindElements: by to selector
• IInteractsWithApps: appPath to bundleId and appId
• ITouchAction.LongPress: el to element

Updated documentation comments for better compatibility:

• INetworkActions.ToggleData: <= to <=
• Removed empty <param> tag in INetworkActions.SetGsmSignalStrength

I'm confused here. Which data type is actually expected by this API? The appium server API does expect a base64-encoded string.

[Dor-bl]

There is indeed an overload that also accepts base64-encoded string.

dotnet-client/src/Appium.Net/Appium/Android/Interfaces/IPushesFiles.cs

Lines 22 to 34 in 44c2c31

	/// <summary>
	/// Saves a string as a file on the remote mobile device.
	/// </summary>
	/// <param name="pathOnDevice">Path to file to write data to on remote device</param>
	/// <param name="stringData">A string to write to remote device</param>
	void PushFile(string pathOnDevice, string stringData);
	/// <summary>
	/// Saves base64 encoded data as a file on the remote mobile device.
	/// </summary>
	/// <param name="pathOnDevice">Path to file to write data to on remote device</param>
	/// <param name="base64Data">Base64 encoded byte array of data to write to remote device</param>
	void PushFile(string pathOnDevice, byte[] base64Data);

I just wanted to make sure the argument that is actually sent to the server is base64-encoded.
